I want to run a locomotive on a different route than original. Are there any restrictions to this operation?
Electrification is the only limit, as in if it's an electric loco then the line must be electrified. TSx doesn't distinguish between OH or 3rd rail, only electric or not
Yes, the AEM can travel on the Hudson line in Quick Drive. I think the TS2021 should sort the OH and 3rd rail.
The AEM7 only travels on the Hudson line IF you run it there. The system works quite well so no need to change it just because YOU don't like it
