So the Ayrshire coast line stretches from Glasgow Central to Ayr with branches from Killwinning to Ardrossan Harbour and Largs. Calling at: Cardonald, Hillington east, Hillington West, Paisley Gilmour St, Johnstone, Milliken Park, Howwood, Lochwinnoch, Glengarnock, Dalry, Kilwinning, Irvine, Barassie, Troon, Prestwick International Airport, Prestwick Town, Newton-On-Ayr. The Largs branch branches off at Kilwinning calling at: Stevenston, Saltcoats, Ardrossan South Beach, West Kilbride, Fairlie. The Ardrossan Harbour branch branches off from the Largs branch at Ardrossan South Beach calling at: Ardrossan Town only. Now unfortunately for the majority of the route there is just the class 380 but Glasgow Central to Paisley Gilmour street also includes the class 314, 320 and 318. And Troon to Ayr includes the class 156.
I would really like a route with the class 320 and it didn’t operate there at that time, but if another ScotRail route were to come to the game (E•G North Clyde line, Argyle Line) then sure, why not. Or they could add 2 timetable modes, one right now (320, 318, 380, 385, 156 via Kilmarnock) and the other back then (380, 314, 156 via Paisley)
