I haven't really myself other than educated guesses based on rolling stock from similar time periods. I gave the Victorian Sprinter railcar 0.8 m/s/s and that stock has a more powerful engine, but max acceleration is also dependent on gearing so could vary a lot.
Acceleration would be something you'd have to FOI to get access to

Acceleration isn't based on anything much more than an assumption, i was not able to find reliable stats for it, if there is a better recommendation i am more than happy to change it.

Hey there, what was your 0.6m/s/s acceleration based on?
