A few things- * I've heard it mentioned that the 150 can sub in for the 101 on some services, but I don't see it as a selectable train. Is it just for AI trains or has this update not come down yet? (PS5) * Could the loco-hauled trains, where you pull a 101, be replaced with Mk2 coaches if you have NTP? * Could extra AI trains (loco-hauled passenger, freight), be added at Darlington, Eaglescliffe, Thornaby, and Middlesbrough? Trans-Pennine, Durham Coast and ECML services using the 45/47/etc Essentially I think everything that's an option in NTP should appear in Tees Valley and vice-versa. West Cornwall too, to some extent. It would make the routes feel so alive - there is a decent range of BR rolling stock.
I haven't seen the 150 on TVL at all but more movement on the line will be lovely to see from NTP and future DLC in the game
