There is one nagging thing that needs to be brought to someone's attention. It is too late to fix it now, but maybe the next go around.
It seems that since the beginning of computer time, train games have done the same thing upon launch. MSTS did it, MSTS II would have done it, the company that inherited MSTS II (and later turned it into a Sea Turtle diving simulator) was going to do it ( I saw screen shots ), I think Run8 has done it, and now DTG has done it in this iteration of their train game.
Why in hell do we get the same three locomotives every time a new and improved game comes out - GP38-2, SD40-2, and something GE from around D-9 era. I mean really, there are hundreds of locomotive models out there, why do the same three keep popping up first and foremost?
