Hey guys today I will be suggesting the ScotRail Class 320 EMU Unit as a new DLC for TSW 3. Photos: The units came into service in the early 1990s and still operate to this day. The Class can operate up to 90 mph unlike the /3 version only being able to go up to 75. This can be Layered onto E-G as from what I know it also runs there with it's mainline being the Argyle Coast Line. Anyway I think this would be a nice addition to the scotrail variety for TSW.
Best off coming with an Argyle Line route; doesn't offer much to Cathcart in its era, it only really showed up around Cathcart after the 314's withdrawal.
