Pk curiously i don't see an option to drive between Ed and GLa which for many decades was the main route in fact the service goes right past my house is there a dlc for it or a mod?
There are four routes between Edinburgh and Glasgow, the only one represented at the moment is the route via Falkirk High. The other routes would likely come as different add-ons due to their length and complexity. Best thing to do would be to make a proposal of the route you would like to see in the suggestions area. I assume you are referring to the Edinburgh to Glasgow via Bathgate/Airdrie line, predominantly run by the Class 334?
No it runs from ED to Livingston then thru Faulhouse, Shotts, Uddingston etc then onto GLA operated by Scotrail.
The Shotts line (though Livingston) is a different route not featured in TSW. The main route now is via Falkirk and that's what's included.
Thats a shame really get to see them go whizzing past my house every day(i live in fauldhouse) so there may be some bias lol
