Two sets were loaned by the Eastern Region to the Scottish Region for a period of 14 weeks. They arrived at Leith Central on the 13th April 1956 and they started running on the Gullane branch (closed to passengers some 25 years previously) for crew training. They were placed in service on the 11th June to determine the suitability of using DMUs on certain routes. One set operated between Waverley and Galashiels, and the other on the Gleneagles, Creiff and Comrie line. This second line became completely diesel worked apart from the 6:00am Stirling to Crieff, the engine of which returned light. The set was stabled in the semi-roofless Perth North shed, from which it ran out empty in the morning to Comrie and returned light at night after working the 6:03pm. Gleneagles to Comrie. The set had a most favourable effect on both comfort and patronage. The set finished on the branch on the 21st July and ran light to Leith Central the following day. After six weeks they were both transferred to the Corstorphine, Waverley and North Berwick line for the remaining eight weeks till 15th September, before returning to the Eastern Region. They formed part of augmented services introduced on the 23rd July on the North Berwick and Corstorphine branches; with other services still steam operated. Example workings on the 8th Aug when set 79056/272 was on the 2:50pm from Waverley and 3:55pm return from North Berwick to Waverley. For the fourteen weeks the vehicles, 79055/6 and 79271/2 were allocated to St. Margarets, and were listed as transferred north on the 4 week period ending 21/4/56, and back south in the 4 week period ending 22/9/56.

So one is justified in having one of these early units on a 1950s based Scottish Layout.
