...What route, what specs, pictures, you basically gave no info other then class 350 and Portsmouth to London which isn't a route in the game.
I could say the same thing about other routes. WCML, ECML, Ayshire Coast Line, Edinburgh to Glasgow, Crewe to Manchester, etc... Yet we don't see it. Just because lots of people suggest something, doesn't mean it will get made. Even if it's on DTG's list then it won't get anounced for ages because it takes so long to make a route. Be patient and you might see it in the future
They can add this, doesn't mean they will A very popular route in TSC though so that might actually put DTG OFF because people sometimes squeal at such duplication
I think you mean the class 450. They run the Portsmouth - London with the 444s. The only route that the Class 350 could be is the Birmingham Cross-City.
If I had a pound for every time I’ve seen ‘the people’ ask for a Class 350 from Portsmouth to London I’d have exactly one pound.
