Throughout the ERS, the timeline of Skarloey Railway starts from 1980, and from there, goes on to address numerous changes on the railway which have shaped it well into the 21st Century.   While the railway has not received any extensions to its running length, it has seen a number of changes to its motive power stock-list, acquiring and then later (at different dates) moving two steam locomotives to the Mid Sodor Heritage Railway; receiving three new Diesels between 1989 and 2004, and of course, the building of the scratch-build locomotive, No.7 – Ivo Hugh, completed in mid-1996.   The composition of locomotives has also been varied over the years.  As part of a long-term agreement with the Talyllyn Railway, Peter Sam and Duncan have both seen long periods of service in Wales, away from the Skarloey Railway.  Peter Sam did make a brief return in 1996 before being sent back during a crisis period on the Mid Sodor Heritage Railway, which saw Edwin Richard called in to finish their extension to Ballamoddey.  Duncan has also been back from late 2007 undergoing boiler work, and returned to Wales for the 2010 season.   However, the locomotive composition of the railway is not the only thing that has changed throughout the ERS, as will be revealed in a yet-to-be-published Extended Railway Series volume, which marks one of the biggest major changes to take place in either the Railway Series or Extended Railway Series.
