It might be hard to properly implement, given they were all scrapped in 1950, but they wouldn't be the first scrapped trains to come to TS. I'd personally love to be able to drive this beast. https://en.wikipedia.org/wiki/Chesapeake_and_Ohio_class_M-1
If we could get a steam era C&O route I'd buy an M-1 DLC right quick. It'd be rather nice to have that part of steam locomotive technology and development represented in Train Sim. At least then we wouldn't have to deal with all the shortcomings of the locos in TS. Though, with the technology of today, it does lead one to wonder if those turbines could've worked successfully if they had been preserved and then brought back into service in this century. But I digress. Edit: Well let's add a slideshow, videos of models, photographs, and a commentary/history video to spice up the thread.
