Excellent idea empty and these to 8 December 2010 the inaugural run on Scotrail network except for Cathcart Circle which would be 3 years later 8 December 2013 to 3 years 6 months 8 June 2014. Even better as a downloadable content train is Mk3 based Class 318 can be sold as a bundle with class 455 BML
The 318 didn't see as much service as the 380 and the 318 is much better suited for the Argyle or North Clyde lines. Plus it's very similar to the 314.
Thank you for telling me about this and I'm wondering is this your local line since you do have knowledge of the rolling stock.
I wouldn't mind a Class 303 as a retro pack with a new timetable. Maybe alongside a Yellow/Black liveried Class 314.
