It would be awesome to have some routes that incorporate Scranton Pennsylvania and Historic SteamTown. Also some more locomotives like the Alco C636 locomotive (potentially in Delaware - Lackawanna livery) and/or the GG1 Electric locomotive in Pennsylvania livery
Alco locos are a great idea for TSW. Let's get more classic diesels. PRR Baldwin RF-16 Sharknose A/B units, switchers, and Centipedes would be awesome to see in game. I'd love to see FM Trainmasters and other FM diesels in game. The PRR GG1 (also PC, Conrail, Amtrak, etc. liveries) is needed for either the Keystone Corridor or NEC lines. Also for NEC/Keystone: PRR E44 Rectifiers.
