Here's a B&O route proposal for TSW. It would go from Brunswick to Cumberland. It would be set in the 1950's. The route is over 95 miles. The Baltimore & Ohio rolling stock would include EM-1 2-8-8-4's, T-Class 4-8-2's, Q Class 2-8-2's, S Class 2-10-2's, P Class 4-6-2's, E-units, SW's, SW1's, SW2's, GP7's, F-units, GP9's, SD9's, FA-2's, FM's, and RF16 Sharknoses.
Lots of good vintage diesels in this suggestion. I'd love the Sharks, FMs, FA-2s, and SD9s. The EM-1s and E-units would be fantastic, too.
I can see some necrobumping on this thread, but as the OP has removed them, I'll keep the thread live for the moment. Please remember, if you have additional information to add to a suggestion, please include it in your original post, rather than posting additional comments.
