I'm already expecting the answer to this question to start out with either "No it's not possible" or "well it's complicated" but here goes:
Is there a way to go in and alter the way a locomotive functions? Like changing the "top speed" of a loco, or the acceleration? I wanted to make repaints of some locomotives but I wanted some of them to be able to go just a *bit* faster, or maybe up the traction to haul just a bit more weight more effectively.
Nothing freakish, I'm not trying to turn a switcher into the jet train.
One specific example is that I wanted to create some fictional repaints of the centipede locos and "optimize" them or whatever for something like a passenger service where they could reach 100 mph. "Just for fun".
I'm sure RWtools will have something to do with the answer, so yes, I have RWtools. I've never used it, though.

P.S. I'm not releasing any of these altered locos on the workshop. As I said, it's "Just for fun"
P.P.S. The word "prototypical" is banned from this thread.

I don't think I changed the right thing though, so I'll put meddling with that on hold till this weekend when all my classes will be done and I can have time to experiment etc. But I think I lied when I said I'd never used RWtools cause I've done repaints before. Oops lol.
