Thomas was one of the first engines who helped to build the railway. He began as a cheeky, fussy engine who began life shunting at Vicarstown. He eventually grew bored being stuck in the yard and wanted to see the world, resulting in a few follies like leaving behind his first passenger train and almost having an accident with delivering some trucks to Edward’s Station. The Fat Controller ended up feeling sorry for him, and knew that he was a special little engine. Thomas eventually proved his worth after rescuing James after an accident. As a reward, that Fat Controller gave Thomas his own Branch Line, which starts from Knapford and ends at Ffarquhar. He enjoys running it as efficiently as he can, with his two carriages Annie and Clarabel, and his friends Percy, Toby, Daisy and Mavis.

	Edward is a kind, patient and experienced engine with a heart of gold.  He has been with the Fat Controller’s railway since the early days, but was sometimes found to be surplus to requirements.  All this changed when Edward was given a chance to prove how useful he could be again, and he has been an invaluable member of the Fat Controller’s engine team ever since. However, some engines still believe that because of his age, Edward is not as useful as the others... time and again, he has been delighted to prove them wrong!  Edward now runs his own Branch Line from Wellsworth to Brendam, working alongside BoCo and keeping a watchful eye on Bill and Ben!

	When Henry first arrived on the Island, he was a cross between Gordon and a nightmare.  Underpowered and unreliable, Henry was often ill and caused the Fat Controller a great deal of trouble.  The problem was solved in the short-term by giving him special Welsh coal, but when Henry had his accident with the Flying Kipper, it provided the Fat Controller with an opportunity to have Henry rebuilt completely. Henry was sent to Crewe, and rebuilt into an LMS Black 5 with a larger firebox and a new shape.  He returned to the Island of Sodor a much better and stronger engine, and the Fat Controller was proud of him.  Henry still has lapses of illness occasionally, but continues to be a really useful engine and a reliable secondary Express engine for Gordon.

	Gordon was the original, experimental prototype for Gresley's A3 Pacifics, and his strength and speed have kept him as the railway’s main Express Engine since his arrival many years ago.  Very proud of his appearance, the big engine can be very boastful at times, which can often land him in all sorts of trouble and awkward situations, such as the time he stalled on a hill not long after his arrival on the Island.  Thankfully, Edward was there to help push, but from that day onward, the hill would be known in legend as ‘Gordon’s Hill’. Over the years, Gordon has settled down to be a true asset to the Fat Controller and a good friend to the other engines, always willing to lend a hand when needed and to put his great strength and ability to good use to help others.

	James is a mixed-traffic engine with a brass dome. When he first came to Sodor, he was painted black and had a dreadful accident with trucks due to useless wooden brake blocks. After being mended, he was given a new red coat which he shows off with pride, and settled down to be Really Useful. He is a very conceited engine, who likes nothing more than to show off his paintwork whilst pulling passengers - but being mixed-traffic he also has his fair share of the goods work and does his best not let the dirty trucks spoil his coat!

	The often naive junior member of the Fat Controller’s engine team, Percy was brought to the railway when the Fat Controller needed a new shunting engine at the Big Station to fetch coaches for the engines.  Even from day one Percy was cheeky and proved he was more than a match for the trickery of Gordon, Henry and James.  But eventually, the work in the big yard became too heavy for him to deal with, and Duck took his place as the station pilot at the Big Station. Percy was reassigned to Thomas’s Branch Line to help build the new Harbour, and later became the Branch Line’s main goods engine, shifting trucks from the yards to the junction and Harbour.  Percy is fun-loving and enjoys playing jokes, which can sometimes get him into trouble.

	Toby was brought to Sodor following the closure of his own line back in England.  He had had little work there following the aquisition of most of his work by the lorries and buses, but by lucky coincidence, was met by a Stout Gentleman and his family who were on holiday in his part of the world and who eventually bought him to solve a problem on his own Railway.  Toby has proved useful for the purpose of running on the Ffarquhar branch line.  He is one of only two engines allowed to run to the Quarry at Anophia (the other being Mavis) and often takes workmen's trains down to the Harbour at Knapford.

	Duck (real name Montague) was brought in originally to replace Percy as station pilot at the Big Station when the workload became too much.  Formerly of Paddington, he is very proud of being Great Western, and has tried tirelessly to instil this ethos into the minds of his fellow engines – often to their annoyance.  But Duck will stand no nonsense from anyone, be it trucks, coaches or engines and throughout his time as the Big Station pilot, he had the yard running like clockwork.  Eventually, his hard work merited him the chance to run his own branch line on the Arlesburgh line, which runs down the coast to meet the Small Railway Engines and carry both ballast and passengers.  He now works this line with the help of Donald, Douglas and Oliver, another Great Western engine.

	When the Fat Controller ordered a Caledonian Goods engine from Scotland, he never quite expected to find two arriving on his railway as opposed to one.  He had ordered No.57646, however, the twin 57647 also arrived as well.  The two refused to tell which was which and left The Fat Controller with the dilemma of choosing between them.  He soon found they both performed equally as good as one another, albiet with both of them running into some kind of bother or another!  But after their performance in the snow in the midsts of a bad winter, he decided to keep them both, which proved a wise choice!  Donald and Douglas are very strong personalities and are the mainstay of the goods work on the railway.

	Oliver came to Sodor in a way very different to the rest of the engines.  His sympathetic crew chose to break away with him and give him the chance of a new life, as opposed to one last gasp with the cutter's torch.  After making a daring escape, they were soon stopped dead in their tracks when they ran out of fuel and couldn't make more steam.  All looked set to be lost until they met Douglas who was doing the late night goods train to the other railway.  He saved Oliver and brought him to the Fat Controller's Railway, where he now works on Duck's Branch line.  He has learnt much from his early days when he was pushed into the turntable well by unruly trucks, and proved to be a useful engine!

	Called by what he is, Diesel is a deceiving, scheming character, who was brought "on trial" to work in the yard. However, when Duck tried to show him around, Diesel took no notice of his advice and ended up embarrassing himself when he moved the wrong trucks. This lead to endless teasing from the trucks, and made Diesel angry, thinking that Duck made them laugh at him. He began causing trouble between Duck and the other engines by telling lies, but was eventually found out by the Fat Controller and sent packing. However, in spite of this, he still charters from Sodor to the Mainland acting as a "spare" engine for heavier work, much to the annoyance of the Sudrian Engines!

	When Thomas had an accident, Daisy was brought in to help Percy and Toby run the Branch Line. But she proved to be troublesome; stuck-up, lazy and stubborn, and only did whatever work she chose. The Fat Controller threatened to send her packing until Percy had his predicament, leaving Toby and Daisy to run the branch by themselves. And after Toby put in a good work for her, she was allowed to stay. Daisy helps Thomas with the passengers and sometimes takes the milk or looks after Henrietta for Toby. But to be fair, although still flouncy, she’s really a sweet engine and takes a liking for Mavis especially.

	Bill and Ben are two saddle tank twin engines. Completely identical, they work at the China Clay pits near Brendam Bay on Edward’s Branch Line, pulling their loads for the Main Line engines and ships in the harbours. They are a mischievous pair, who love playing jokes and teasing the other engines - especially Gordon.  The twins are also frequently used in other Quarries across the Island, often found working with Mavis at the new Centre Island Quarry, and have been used to shunt in the Harbour yards when needed.

	BoCo first arrived on Sodor as a visitor and had the misfortune to encounter Bill and Ben, who mistook him for a thieving “Diseasel”, causing him great confusion. But after having proved to being Really Useful during his stay, the Fat Controller welcomed him as “one of the family”. BoCo lives at Edward’s Station ad helps Edward run his Branch Line, but he is always welcomed anywhere. He’s a kind natured diesel with a sense of humour, which makes handling Bill and Ben much easier over the years!  Sadly, BoCo is one of the only members of his class left, the other undergoing a long-term restoration at the East Lancashire Railway.

	Mavis was first brought to shunt trucks at Ffarquhar Quarry. Her wheels are hidden by cowcatchers and sideplates like Toby’s. But being young she was full of her own ideas, and caused Toby many a headache by constantly rearranging his trucks and ignoring his advice.  But an unfortunate accident soon provided a chance to help Mavis see sense.  Her plans to go further down the line by asking the trucks to bump her also went awry, leaving Toby stranded on a collapsing bridge when they bumped him instead!  After a daring rescue, Mavis was given permission by the Fat Controller and Quarry Manager to go down the line to the yards with trucks, and with help from Toby she settled down and became a more mature engine.  Mavis is now a shining example to all of the other engines, and often helps provide guidance where needed.  You can often find Mavis shunting trucks with Bill and Ben at Centre Island Quarry.

	The Fat Controller had decided to bring in another diesel to help Bill, Ben and BoCo at the China Clay quarry. However he didn’t bargain for Derek!  Derek is a kind, jolly sort of chap, but his locomotive type has a design flaw, causing him to suffer dearly from teething troubles and constant breakdowns, and spends many a day at the Works. Despite their dislike for most diesels, Bill and Ben eventually felt sorry for him for trying to help out.

	‘Arry and Bert are as devious and spiteful as Diesel himself. They work in the Sodor Iron Works, bringing in scrap metal from the scrapyards to melt down and use again. They believe that all steam engines are smelly and useless and should be scrapped.  But as they can’t get away with that under the Fat Controller's watchful eye, they just have to put up with teasing them instead!

	Salty is an old diesel who has travelled the world and seen many amazing sights.  He works hard and seldom complains, and he always entertains the engines with his endless amounts of stories and tales from the places he has visited.  He is also well known for keeping the trucks in order by singing sea shanties as they work!  Salty has a big heart and always comes to the aid of any engine.

	Harvey came to Sodor on a rough patch. Before giving a demonstration to earn his place on the railway, he was hurt by the other engines' unkind comments about his strange boiler crane arm. But when Percy had a derailment, Harvey made quick work in clearing up the wreckage and making a good enough impression to stay on Sodor. He is a kind, tough engine used for smaller jobs that his arm is best suited for and makes short work of any task he is given.

	Arthur is the largest tank engine on Sodor, bought from the LMS to shunt trucks and haul freight. He was famous for his “Spotless Record” for not having been in trouble or made a mess. This made Thomas jealous and forced him to play a disasterous trick resulting in Arthur having an accident and spoiling his record. But he soon left his past behind and continues to work hard in a no-nonsense manner. He is now in charge of the Fishing Route by a coastal village, where the glorious smell of fish hangs in the air for him to enjoy!

	Fergus has been working on the Island of Sodor for some time but has never really been noticed from having spent many of his years at the Cement Works. He is known to be a strict engine, knowing every rule and regulation by heart, and is constantly nagging the other engines to “Do It Right!” if they ever did wrong. But he is a kind engine as well, and prefers working with sensible engines who complete their jobs without fuss.

	Emily is a beautiful Stirling Single engine, brought to Sodor to help with passenger duties. She is one of several female steam engines residing on Sodor and works well. But sometimes, Emily tends to become a “bossy buffers”, as she tries to help her friends by correcting their mistakes and encouraging them to improve. Even so, she is a real “sweetie” and has her own two carriages, which she delights in carrying passengers in them.

	Murdoch is one of the largest engines on Sodor, and was brought to the Island to pull heavy goods trains for long distances.  Despite his size, he’s actually a gentle giant and much prefers some Peace and Quiet outwith the hustle and bustle of the yards - and there is no better place for him than a run through the countryside..  However, he has learned from previous experience that being in the company of chatterbox engines can often be far better than the baa-ing of sheep, which he once found to be too much for him to bear!

	Molly is a yellow steam engine who has been brought by the Fat Controller to pull empty trucks to the coaling plant.  Some of the other engines teased her about that, she didn't feel her job was important enough, and this made her sad.  Thomas tried to cheer her up by making everyone think that she had an important train to pull, but at the last minute everything went wrong. In the end, Molly realised how important her job really was, and she knows now that pulling empty trucks can be just as important as pulling full ones.

	Poor old Neville fell victim to a series of "Chinese Whispers" which were spread among the engines, resulting in Emily thinking he was going to bump all the steam engines.  He looks a lot like a Diesel, when he is in fact a steam engine, and a lot of the other engines didn't like him at first.  But once Neville's true personality was allowed to shine through in spite of the rumours, the others knew he was a really useful and kind engine after all!

	Dennis is a very lazy diesel who tries to take advantage of others and depend on them to do his work.  When we first meet Dennis, he tries to trick Thomas into giving up his afternoon off to help the lazy Diesel.  Dennis will always create excuses to get out of work, but usually gets caught in his lies, and is always very sorry...until he finds another oppurtunity to get out of work again!

	Rosie is a friendly little tank engine who idolises Thomas, and wants to be just like him.  And although once, he was keen to get away from her, Rosie proved her worth by coming to the rescue and helping him when he ran into a landslide!  Rosie is plucky and determined to do work that the bigger engines think she cannot.  While trying to help Emily with the Fun Fair Special, she ended up taking half of the train and losing the trucks when she strained the couplings.  But, she knows the importance of being really useful and despite being young and inexperienced, she always tries to learn from her mistakes.

	Whiff is a kind hearted, but nevertheless niave little engine who often takes on some of the dirtier jobs on the Island, which commonly involves taking the Island's refuse to the dump.  When Whiff first arrived on Sodor, some of the other engines thought his untidy and grubby appearance to be a great joke, but Whiff more than proved to them that looking splendid is no substitute for being a really useful and hard working engine!  Nowadays, Whiff can be found shunting trucks at the new Sodor Recycling Plant with his friend Scruff.

	Billy is an impetuous little tank engine, who thinks that he knows better than the other more experienced engines on the Island. When Billy first arrived on the Island, he wouldn't listen to a thing that Thomas advised him to do; he thought that he knew it all and Thomas was being a very bossy engine.  However, Billy soon learnt his lesson when he ran out of coal and water, and realised that he didn't know as much as he first thought.  He knows now to listen to the advice of his elders, and not to do things his own way!

	Stanley was brought to the Island to help during the construction of Great Waterton, and soon became very popular among the engines of Tidmouth Sheds in Thomas's absence.  At first, Thomas was jealous, but he soon found that Stanley is a hard working, friendly, determined and resourceful engine who will do his utmost to help his friends out of jams and tricky situations, and that's what makes him so likable.

	Victor is a small Hispanic engine from Cuba, who was brought to Sodor by the Fat Controller to help run his Steamworks.  Victor is kind, friendly and always willing to provide advice, guidance and help to the other engines whenever he feels they require it.  He keeps a particularly watchful eye over Kevin the Crane, as the young crane tries to find his way around, while muddling through his mistakes and mishaps.  But although Victor is friendly, he takes work very seriously and stands no nonsense whatsoever from troublemakers, particularly the naughty Diesels!  Victor is the only narrow gauge engine in the Fat Controller's engine fleet.

	Hank is a big, bold blue engine from the United States of America, and is easily one of the biggest engines ever to tread wheel on the Island of Sodor.  Hank means well in his manner and is always willing to help the smaller engines with their duties, as shown when he first arrived and had to help Thomas out when the plucky little tank engine took on more than he could handle.

	Flora is a cheerful and attentive little steam tram who has been brought to help work on the new Great Waterton Tramway, working alongside Toby as Sodor's other steam tram.  When Flora first arrived on Sodor, she helped Toby lead the first annual Great Waterton parade with the other Steam Team Engines, and received her very own special green Tram Car to perform her passenger duties.

	Charlie is well known on the Mainland for being the most fun engine ever, and is the favourite engine of the Mainland Controller.  He came to Sodor to help the Fat Controller, and had heard that Thomas was even more fun than he was.  But after his first day on Sodor, Thomas and the other engines taught Charlie that work has to come before play if you want to be a Really Useful Engine.  So while Charlie is still a fun loving scamp eager for play, he knows also that working hard is more important than ‘playing’ hard.

	Stepney is an engine from the Bluebell Railway in Sussex.  He was the first engine on his new Heritage Railway to be ‘saved’ from scrap, and remains a popular fixture on the railway to this day.  Stepney first made an appeared in his own Railway Series book No.18 – Stepney the Bluebell Engine, promoting the efforts of the Bluebell Railway.  His stories were later adapted into the television series where he was rescued from scrap by Rusty the little Diesel.  Stepney is cheerful, enthusiastic and loves to work.  During his visits to Sodor, he has run a special train for an important person – which caused Thomas to be shunted on his own branch line; accidentally held up a Cricket match when he took their ‘one and only ball’ for a ride down the line, and helped Duck pull a heavy train when a boastful Diesel became indisposed... however, he almost came to a sticky end when he met ‘Arry and Bert at the Smelters... but luckily, he was saved again by the Fat Controller!

	Spoilt and big headed, Spencer is the Duke and Duchess of Boxford’s Private Engine, and he takes them everywhere they go. Gordon felt threatened when he learned that Spencer was the fastest engine in the world - faster than him even! But in spite of his endless bragging, it doesn’t take too long before Spencer is put in his place, thanks to his own self-importance and stupidity.  However, while often portrayed as a buffoon, he has shown that he does have a level of cunning and intelligence when he tried to stop Thomas from getting Hiro repaired...

	Like most visiting Diesels to Sodor this one proved no exception to the rule of being rude and rather above his station!  However, like all of his kind, he got his just deserts when a bowler hat was sucked into his air-intake during an inspection, and prevented him from pulling the Express, which Duck and Stepney had to take for him instead! He left without saying goodbye to anyone and left two things behind - a battered bowler hat and a rather nasty smell!

	City of Truro is reckoned to be the first British locomotive to exceed 100 Miles per Hour, acheiving a speed debated to this day as 102.5mph.  He and Duck were supposed to get on famously during his stay on Sodor, talking about all things Great Western.  However, like Henry and Flying Scotsman, City of Truro sparked jealousy within Gordon and gave the big blue engine ambition to break City of Truro's record.  He did this to no avail, and instead lost his dome in the process as it was blown off by a strong gust of wind! City of Truro, like Flying Scotsman, is part of the National Collection.

	Hiro is a gentle giant engine who came from an Island very far away to work on the Sodor Railway when it first opened many years ago.  Hiro was the strongest engine on his Island, and earned the name, 'Master of the Railway' both there and on Sodor.  But Hiro began to break down and he was laid aside to await the arrival of parts from his Island... which sadly never came.  Hiro was lost for a very long time, but was eventually rediscovered by Thomas who tried to restore him to his former glory.  Hiro became a friend to all of the engines throughout this time, but he eventually wanted to go home to his Island.  But Thomas was keen to remind him - Sodor would always be his home too.

	Annie and Clarabel are Thomas’s faithful coaches, given to him to carry passengers on his Branch Line. Annie can only carry passengers and travels nearest to Thomas, while Clarabel carries passengers, luggage and the guard. Both are quite old, but they and Thomas have a good friendship and often act as voices of reason whenever Thomas gets worried or above himself.

	Henrietta is Toby’s coach and faithful companion. Despite seemingly lacking a face, Toby is attached to her and can tell how she is feeling. Henrietta was very lucky to live on Sodor with Toby when their old line closed, and was glad to miss being made into a henhouse!  Henrietta is one of the few characters on Sodor not to have a face in the TV Series - and only ever appeared with one in the Railway Series books in 2007!

	The Troublesome Trucks are the “Rascals of the Railway”. They come in all shapes, sizes and types, and love to cause grief and despair for whichever engine has to take them out. They have been known to cause constant accidents if their engine is careless and annoy them most by singing rude songs, loud and long! Only the most experienced and strongest of engines can keep them in order and they are quick not to fool with those who do!

	S.C.Ruffey acts as the leader of the trucks. Although looking past his prime, this old wagon still has some tricks up his sleeve, teaching the younger trucks how to be troublesome and irritating!  Like the Spiteful Brakevan, he liked to cause trouble for the engines, this time around Oliver, who had landed in the turntable well, which Scruffey enjoyed teasing him about.  Toad the brake van had a plan that soon put him in his place, and Oliver (accidentally of course!) hauled him to pieces when trying to move a heavy goods train!  He was rebuilt, and has since learnt his lesson.

	Toad escaped from scrap along with Oliver. The two of them are very good friends as Toad helps to keep Oliver’s trucks in order.  He is known to be very pleasant and arguably protective over Oliver's best interests, particularly when he finds himself running into trouble! This elderly van has much respect for all engines, referring them to as ‘Sir’ or ‘Miss’, as he does so when speaking to ‘Mr Oliver’.

	This spiteful Brake Van took pleasure in Douglas's misfortune and launched a vendetta against him to have him sent back to Scotland.  He was soon put in his place by Donald, and behaved better for a while, until he had another chance for mischief, this time with James as his victim.  It was his ultimate undoing when he forced the trucks to hold back, and causing Douglas, pushing from behind, to smash him to pieces...with no chance of repatriation, thank goodness!

	Old Slowcoach was a wonderful Luxury Coach in the old days. She would travel on fine Great Western/Victorian lines then, but as time went on she was soon branded as Old Fashioned and spent most of her lonely years in a scrap yard, waiting for her fate. But luckily, Thomas and Percy discovered her and had her restored to her natural beauty, where she is still useful around Sodor.

	We were first made aware of the Breakdown Train when Thomas used it to rescue James from an accident in a field on his first day.  It consists of a Workman’s coach, some flat trucks and two large cranes, built to carry engines, coaches and trucks - very useful whenever they are required to rescue a derailed train or engine.  Also been seen frequently when maintenance work is needed on the railway.

	Rocky is a cheerful big crane who wants to be friends with everyone on the Island of Sodor.  When he first arrived, some of the engines thought that because Rocky couldn't move on his own, he wouldn't be useful; but he soon proved everyone wrong when he managed to clear a pile of pipes off the line and lift Gordon back onto the track!  Now everyone knows Rocky is a really useful crane, used greatly for maintenance and rescue operations around the railway.

	Hector is one of the biggest and most modern trucks on the Fat Controller's railway.  When he first arrived, he was one of the most fearsome and terrifying trucks that the engines had ever encountered.  Thomas soon found that Hector never meant to scare anyone, but that he was actually scared of being filled with coal for the first time.  Now Hector is as useful as can be, and is no longer afraid of trying new things!

	Skarloey and his brother Rheneas are the oldest engines on the Narrow Gauge Railway - both built in 1865, and approaching 150 years old like their counterparts Talyllyn and Dolgoch on the Talyllyn Railway within the next decade! Skarloey maybe old and tires out easily, but he always helps his friends and never stands for any nonsense whatsoever. He is a great friend with Edward, who used to bring passengers to travel on Skarloey and Rheneas’s trains years ago. This little old engine has great respect for all railway staff and knows the importance of passengers being their “coal and water” to keep their wheels running.

	Rheneas and his brother Skarloey are the oldest engines on the Narrow Gauge Railway. Rheneas is a real “Gallant Little Engine”. Many years ago, he helped to keep the railway open by bringing his passengers home on one cylinder. As a reward, he was sent away for repairs and was warmly welcomed seven years later. A brave, daring little engine, Rheneas has always brought his train on time and never gives up the fight.

	Sir Handel (formerly named Falcon) worked Duke’s old line and, like Peter Sam, was kept in his place by Duke. Despite being one of the more elderly engines on the Skarloey Railway, he is rather “highly sprung”, believing only what he thinks is right, and his bad temper normally ends him up in trouble. He was eventually sent to work in the Stone Quarry out the way where he came back a better engine...but he still shows traits of his previous behaviour now and again!

	Peter Sam (formerly Stuart) is a busy, bustling little engine, who enjoys hard work and hardly grumbles. He was taught by Duke and has great respect for him. Although susceptible at times, he’s a kind engine and always proves his worth by being a happy little worker. But life wasn’t perfect for Peter Sam - following an accident with slate trucks, his funnel became damaged and wobbly; during winter, it broke off altogether thanks to an icicle in a tunnel. But luckily, he was given a “Special Funnel”, which helps him work harder than ever.

	Rusty is a little diesel engine, who was brought to help when Skarloey was sent for repairs. A friendly hard worker, he is constantly working up and down the line, repairing all the tracks, bridges and tunnels along the Skarloey line, keeping it generally maintained.  Although sometimes given hassle by Duncan for being a diesel, Rusty's good nature often shrugs it off.  Simply loves adventures and a true friend for life.

	Duncan was brought as a spare engine after Peter Sam’s accident.  He keeps busy and means well, but can be bouncy and rude, gruff in his attitude. He enjoys nothing more than doing his Rock ‘n’ Roll, which sometimes leads to his undoing, and hates not having a polish or being overworked. Overall, a kind engine who is a little misguided and misunderstood.

	Duke is one of the oldest of the Skarloey Engines, built in 1880 at Boston Lodge works on the Ffestiniog Railway. He used to work on his old line with Stuart (Peter Sam) and Falcon (Sir Handel). But when their line closed, Duke was locked away in a shed and remained there long after his shed was hidden from view by trees and bushes. He was restored, however, 25 years later by travellers who rescued him and brought him to his new home. The other engines are fond of Duke and his tales of “His Grace” - his insight and knowledge make him very wise indeed, despite sometimes mentioned by his nickname: “Granpuff”. And whenever the other engines do that he thinks is wrong he would be heard to remark: “That would never suit His Grace!” Duke was registered as Skarloey Engine number 8, however he doesn't wear the number for reasons best known to the Railway Management or to the Rev Awdry himself!

	Fearless Freddie has spent a great deal of time away from the railway for reasons very much unknown, and was once the fastest engine in the hills.  But in his old age, Freddie soon discovers that he's not as fit and fast as he once was. But nonetheless, he's still knowledgable of the old tracks through the hills and uses them to his advantage!  Freddie is caring and friendly, and will always do his best for his friends, such as the times he looked out for a new bell for the Thin Controller's new bicycle, and when he tried to organise the Christmas Party at the Wharf for Colin the Crane.

	Bertram is a little narrow gauge engine. He used to work at the old mines near a forgotten castle, but when the mines closed he was put away in a shed for safety. Toby and the Fat Controller discovered both the mine and castle, and it was decided that both would make fine attractions. Toby mistakenly thought Bertram was the “Old Warrior” ghost, but discovered it was a nickname for him being so brave. Although rarely seen these days, Bertram works hard carrying visitors around the restored mines he used to work in all those years ago.

	Smudger/Stanley was a complete show-off, as Duke remembered him in the old days of Duke's Railway.  The cocky American engine rode too roughly and often came off the rails as a result.  He also took very little notice when Duke told him what he was doing wrong.  He soon got his comeuppance when the manager decided that he had found a use for him at last...and Smudger was turned into a generator/pumping engine at the back of the old shed.  Having heard what happened to him, it turned the attitudes of Stuart and Falcon around into Really Useful Engines!

	Mighty Mac are a Double-Fairlie locomotive on the Skarloey Railway, with two boilers and two personalities!  Mighty is the older of the two, while Mac is the younger and more insensible end!  When they arrived on the railway, neither end were able to agree on which way to go when taking passengers into the mountains, both have since learnt sense and have agreed to work together in future.
