Day Of The Diesels

A Little About Day of the Diesels

DAY OF THE DIESELS is the fifth Direct-To-DVD Special produced by HIT Entertainment.  It is the first of the Thomas Specials not to have Thomas as the lead character.

Day of the Diesels sees the full return of Diesel 10, the main villain from Thomas & The Magic Railroad, to the Thomas TV Series as a lead player in the CGI series.  The special sees Thomas’s best friend Percy taking the role of leading man for the first time in a Thomas & Friends special, as his loneliness and frustration is influenced and manipulated by Diesel 10, as Thomas spends more time with new friends Belle and Flynn than him.

Day of the Diesels sees Diesel 10’s home, Vicarstown Dieselworks come to the fore for the first time – along with its quirky inhabitants, Dart and Den, who run the Dieselworks and repair the Fat Controller’s Diesel engines... under the instruction of Diesel 10 of course!

Day of the Diesels was written by Sharon Miller, the Head Writer for Thomas and Friends.

BRWS' Day Of The Deltic

Fancy a story with a little more bite and intrigue?  The British Railway Series produced an episode chronicling the early runs of the Deltic, the first Main Line Diesel locomotive.  Here, the mysterious and threatening new arrival spreads fear and intimidation throughout Copley Hill...

Day of the Deltic - on BRWS.com


Thomas puffs happily along

It’s another idyllic, happy summer’s day on the Island of Sodor.  Henry is pulling a goods train, Emily is pulling a passenger train on the Branch Line, and Thomas is puffing happily along the tracks. 


Everyone is happy and enjoying the sunshine.  But the happy atmosphere changes very quickly as Thomas sees the blue sky turning black, and the air turning thick and smoky – there’s a fire at Farmer McColl’s farm!

Thomas finds Percy fighting the fire

Thomas races up to find Percy already there helping to fight the flames, using water from his tanks.  The Firemen, Farm Workers and the Fat Controller, who is organising the efforts to save the farm building, fight the flames valiantly, but it’s not enough. 


Percy is worried – but from out of the smoke, a bell rings loudly as help hurries toward them.  It’s a new engine called Belle, who has arrived just in time to help fight the fire with her special water cannons.

Belle fights the flames

Belle blasts the building with her big water cannons and begins to turn the tide against the raging flames.  Thomas and Percy are amazed at what she can do and look on in amazement.  Very soon, the fire is out and everyone is safe again, but the three engines are thick with soot and dirt from the smoke. 


The Fat Controller congratulates them for their effort, and sends them to the Washdown for a scrub – but Belle can’t move.  She’s used all her water fighting the fire.  Thomas kindly offers to shunt her to the Steamworks with Percy – who reluctantly agrees, despite being late for his mail trucks.

The Fat Controller contemplates a new Fire Engine

The Fat Controller is pleased with Belle – but he knows that she cannot fight fires on her own.  Belle knows just who could help – her friend, Flynn the Fire Engine. 


The Fat Controller agrees and goes to make the arrangements for Flynn to come to Sodor, leaving Thomas with the task of showing Belle around the Island... whilst Percy is left to deliver the mail on his own.

Devious Diesel talks to Percy

The next day, Thomas begins spending the entire day with Belle.  But meanwhile, poor Percy is left to feel sad and alone. 


Devious Diesel sees Percy feeling low at the Docks, and takes advantage when he sees Percy again at Knapford Station, pointing out how much fun Thomas and Belle are having together – without Percy’s company...

Diesel follows Percy to the Steamworks

Diesel meets Percy again at the Steamworks, where Thomas and Belle are laughing and chattering with Victor.  Belle asks Diesel if the Diesels have a place just like it.  Diesel is meek and makes coy mention of the Dieselworks, before slipping away quietly. 


Thomas tells Belle that Sodor Steamies don’t go to the Dieselworks because it’s not a very nice place to visit – and it’s full of devious Diesels... once again, Thomas puffs away to shunt trucks with Belle, without speaking to Percy.  This makes the little green engine very sad indeed.



When Percy is delivering mail at Wellsworth Station, Diesel oils up again and begins to make Percy feel even worse by telling him that Thomas has no time for him anymore.  Percy asks Diesel if he would like to deliver the mail with him – but Diesel declines the invite, he has to go to the Dieselworks and see his friends there, once again, leaving Percy feeling lonely and friendless.

Percy and Diesel at the Docks

The next day, the Fat Controller gives Percy the special job of delivering Flynn’s hose to the Search and Rescue Centre. 


While he is waiting at the Docks, Diesel rolls up alongside him again – this time, preying on Percy’s sadness and loneliness, Diesel tells Percy that his friend at the Dieselworks is eager to meet him, and wants him to visit.  This cheers Percy up, and puts a devious smirk on Diesel’s face as well... he can see his plan is working and is relishing every moment of what he is doing.

Thomas and Belle chat with Percy

But he scurries away just as Thomas and Belle puff into the Docks.  This time, Thomas stops to chat with Percy – but declines an invite to deliver Flynn’s hose to the Rescue Centre.  He and Belle are to take the children to the seaside for a day out at Bluff’s Cove. 


Percy feels cross at being left out, and heads off to deliver the hose to the Rescue Centre.  But on the way, he’s faced with a difficult choice.

Percy has a difficult decision to make

On his way to the Rescue Centre, Percy arrives at a Junction.  The right track will take him to the Rescue Centre – the other to the Dieselworks... all the while, Percy is thinking about what Diesel and Thomas have said. 


There are good reasons to go to the Dieselworks, but there are also good ones to stay away from it.  But Percy’s loneliness overwhelms him and he chooses to go to the Dieselworks, instead of delivering Flynn’s hose straight to the Rescue Centre.

Diesel 10

Percy is unsure when he reaches the Dieselworks, but creeps in cautiously toward the entrance past the dirty old buildings and worn out scrap metal lying scattered around the yard.  It is as unpleasant as Thomas described, and a whole lot more besides! 


Percy feels brave for being in such a strange and scary place, but this is shortlived as he comes closer and closer toward the Dieselworks building... and face to face with the smirking Diesel 10 who slithers out of the Dieselworks to meet Percy as he approaches.

Diesel 10 with his gang

Diesel 10 plays upon Percy’s insecurities and flatters him to win his trust, before leading Percy into the Dieselworks to stop for a while.  There, he meets two new Diesels who he has never seen before – Dart and Den, who run the operations at the Dieselworks.  Percy and the Diesels chat for a very long time, and Percy nearly forgets about delivering the hose to the Rescue Centre for Flynn.  Diesel 10 assures him he needn’t worry – and orders Dart to take it instead.

Mavis is shunted into the Dieselworks by Salty

Just then, Mavis is shunted in for repairs by Salty.  Mavis is confident that Den will fix her up, but Salty passes a comment on how poor his facilities and tools are – which makes Den feel sad.  Percy suggests that they ask the Fat Controller for a new Dieselworks.  Diesel 10 uses the opportunity to explain the ‘plight’ of the Diesels to Percy – and tells him that the Fat Controller won’t listen to Diesels, he only listens to steam engines.  Percy then resolves to ask Thomas to ask the Fat Controller, knowing that the Fat Controller always listens to Thomas, and hurries off to find him.

Flynn meets the engines at the Steamworks

Meanwhile at Brendam Docks, Flynn is being unloaded by Cranky with a crowd of engines waiting to see him arrive.  Percy arrives at the Steamworks and pulls up alongside Thomas, eager to tell him all about Diesel 10 and the Dieselworks, before he is interrupted by the Fat Controller, who introduces Flynn.  Thomas tells Percy that he has been asked to show Flynn around the Island, as he had done with Belle – and puffs closer to his new friend to chat – leaving Percy alone and sad.  Poor Percy puffs slowly out of the Steamworks and back to Tidmouth sheds.

Dart moans about Happy Hook

The following morning, Percy puffs back to the Dieselworks where Diesel 10 is eager for news and developments... which Percy cannot give.  But Diesel 10 finds something else to manipulate Percy with when Dart bashes into Happy Hook – the Dieselworks’ defective crane.  Diesel 10 casts up the fact that the Steam engines have Kevin at the Steamworks – whilst they have nothing of use.  This sends Percy racing off again to find Thomas, in the hopes that he will speak to the Fat Controller – but instead, he finds Kevin at the Steamworks.

Percy tells Kevin about the Dieselworks

Percy explains that the Diesels don’t have a working crane at the Dieselworks, and encourages Kevin to come with him and work there instead – telling him that he’d be a ‘hero’ to them.  Kevin is impressed – but before Percy can say anything else, Thomas puffs in asking about Flynn’s hose – it’s not at the Search and Rescue Centre... Percy tries to tell Thomas that his new friend delivered it, and also tries to explain about the Dieselworks, but once again, Thomas is too busy to listen and puffs over to Victor instead to tell him about the hose not being in the right place. 

Percy looks for Flynn's hose

Kevin is still keen on Percy’s idea of him being a ‘hero’ and tells him that he wants to go with him to the Dieselworks.  But before Percy can say anything more – Victor scolds them both for chatting and sends Percy on his way to find Flynn’s hose.  Percy first checks at the Sodor Search and Rescue Centre, just to make sure that Dart has not placed the hose in the wrong shed - but it soon becomes apparent that it is not there at all.


So Percy puffs all over the Island all day long, but he cannot find any sign of the hose.  Finally, he puffs home, tired and exhausted to Tidmouth Sheds, where there is a very big surprise waiting for him.

Percy is upset

Flynn is in Percy's place!

There is Flynn standing bold as brass in Percy’s berth at Tidmouth Sheds, right next to Thomas.  Flynn kindly explains that Thomas said it would be OK for Flynn to wait there until Percy came back, but Percy still feels very sad and upset – Thomas doesn’t feel like his best friend anymore, and he decides it’s time to spend the night elsewhere.  Percy tells Flynn to stay in his berth, and puffs away to help his new friends at the Dieselworks – after a quick stop-off at the Steamworks first...

Kevin arrives at the Dieselworks

Percy puffs quietly into the Steamworks where Kevin is tidying up.  Percy tells Kevin that the Dieselworks need him right away.  Percy loads Kevin onto a flatbed and they slip past the sleepy Victor and on to the Dieselworks, where Diesel 10 is delighted to see his new crane, and he sets to work with Dart and Den to repair Mavis at once.  But Diesel 10 is less than impressed to learn that Percy still hasn’t asked Thomas to speak to the Fat Controller – and encourages him to bring Thomas to the Dieselworks, where they will have his ‘full attention’.

Percy arrives back at Knapford

The following morning, Percy puffs proudly back to work and into Knapford Station where the other engines are waiting.  Thomas hurries in – he has been very worried and been looking everywhere for Percy, but Percy doesn’t care and tells the other engines that he spent the night at the Dieselworks with his ‘friends’.  The other engines are shocked when Percy tells them about Diesel 10 – but there’s another surprise in store – Gordon thunders in with the news that Kevin has disappeared from the Steamworks.  Percy calmly explains that Kevin is at the Dieselworks – but then remembers that he didn’t ask Victor’s permission to take him...

Swing The Hook!

However, Kevin is having a wonderful time at the Dieselworks, playing ‘Swing The Hook’ with Happy Hook.  But Diesel 10 is not keen on the game at all and orders Kevin to get back to work at once.

Percy explains to Victor

Finally, Percy has the attention of the other engines at the Steamworks, and tells everyone about the state of the Dieselworks and why he took Kevin.  Victor is still upset – he needs Kevin at the Steamworks.  Percy decides to use this to his advantage – he tells Victor that Thomas must go to the Dieselworks to bring Kevin back.  But Victor refuses to let the matter lie and steams crossly away to speak to the Fat Controller about the matter at once, whilst Percy steams back to the Dieselworks ahead of Thomas.

Diesel 10 has a devious idea!

Diesel 10 is pleased that Percy has finally done what he wanted, and is even more pleased to learn that Victor has left the Steamworks... Diesel 10 decides it’s time to do something ‘very special’ – they’re going to take over the Steamworks, and Percy is going to lead them! 


Diesel 10 is convinced he can use the Steamworks as a bargaining tool against the Fat Controller – and continues to make Percy think that he’ll be a ‘hero’ for helping the Diesels’ cause.  Percy is concerned for Thomas, but Diesel 10 assures him that no harm will come to either him or Kevin.

Thomas falls into Diesel 10's trap

Thomas puffs into the Dieselworks to collect Kevin, but neither Den, Dart or Diesel 10 are prepared to co-operate with him.  Den and Dart tell Thomas to come with them to the back shed, where they can “take care of him...” Thomas hopes that his friend Percy will see sense and try and help him – but Diesel 10’s flattery has gotten the better of him – and he’s soon leading the charge of Diesels out of the Dieselworks and on to the Steamworks, ready for their takeover, whilst Thomas is led to the back shed by Dart and Den, still calling out for his friend’s help.  This time though, it’s Percy’s turn to ignore him.

Diesel 10 is thrilled / Percy is worried

The Steamworks is completely deserted when the Diesels arrive.  Percy feels proud to have helped his new friends, and is sure that Diesel 10 will praise him for a job well done – but instead, Diesel 10 is thrilled to finally take control of the Steamworks, proclaiming that they will never give it back.  Percy is shocked and pleads with him, but Diesel 10 calls him a “Silly steamie” and snaps his claw to frighten Percy.  The Diesels proceed to run amok in the Steamworks, leaving poor Percy feeling very silly and ashamed.  It’s time to put everything right again – and he decides to start by saving Thomas from the Dieselworks.

Diesels Go Wild!

Percy asks Flynn and Belle for help

But when he arrives at the main shed of the Dieselworks, he finds it’s caught fire.  He then hurries to find Belle and Flynn at the Search and Rescue Centre and urges them to help him.  But there’s a problem – they still haven’t found Flynn’s hose.  Percy tells them that Dart was supposed to deliver it for him, but Rocky tells him that he never did.  Percy realises his mistake for trusting the Diesels, but knows that the hose must still be at the Dieselworks.

Steamie Stand-off!

Percy leads Belle and Flynn to the Dieselworks to fight the blaze, which has spread throughout the building.  Percy hears Thomas whistling for help and hurries to the back shed, where Den and Dart are standing guard.  Percy demands to know where Flynn’s hose is, but they both feign ignorance.  Percy is standing no nonsense and tells them it’s an emergency – Dart caves in and tells them it’s in the rubbish around the back.  Belle and Flynn hurry to retrieve it, whilst Percy orders Dart and Den to let Thomas go.  They refuse to move until Percy reminds them that the Dieselworks in on fire, and they will all be in danger if they stay where they are... Den and Dart move quickly after that!

Flynn and Belle fight the flames

Thomas and Percy buffer up to Kevin’s flatbed and hurry away from the back shed.  They arrive to find Flynn and Belle valiantly fighting the flames at the front end, and cheer them on until they win the day and save the Dieselworks from the blaze.  And when the work is done, Percy and Thomas prepare to steam back to the Steamworks and save it from Diesel 10 and his gang of devious Diesels.

Super Steamies Vs. Devious Diesels

The Fat Controller scolds Diesel 10

Diesel 10 is levelled

Along the way, the engines meet Edward, Henry, James, Gordon, Toby and Emily, and together, the engines puff all the way to the Steamworks to face Diesel 10 and the Diesels.  Thomas and Percy speak to Diesel 10, and offer to help him and his friends by talking to the Fat Controller about a new Dieselworks.  Their chance comes sooner than expected.  The Fat Controller’s car rushes into the Steamworks, and he is furious to see what is happening.  All of a sudden, Diesel 10 isn’t so menacing... and he comes over very coy when scolded...

Diesel 10 is happy - the Dieselworks will be fixed

Percy, Thomas and Kevin each try to explain Diesel 10’s frustration with the state of the Dieselworks, and why he has chosen to take the course of action that he has done.  Finally, Thomas finally asks if the Diesels can have a new Dieselworks to set things right.  The Fat Controller tells the engines that he had been planning to build one for the Diesels all along – it was taking time, but he assures Diesel 10 that it would be worth waiting for.

The Dieselworks is repaired

Together, the steam engines and Diesels work to rebuild the Dieselworks and make it as good as new.  Eventually, the work is done, and all the engines stand proudly at the reopening of the Dieselworks.  The Fat Controller gives a speech, saying that the new Dieselworks is all the more special because it’s a shining example of what can happen when “Really Useful Engines work together!”


But the Dieselworks is not the only thing to be renewed.  The friendship between Thomas and Percy is put right again, and the two best friends get back on track once again!
