Would find it very usefull if i could select a locomotive or consist with the locomotive off and cold to see how i go about starting it up and put to the test some of the knowlege.
Seconding this - I'd love this as a feature. Maybe a toggle in the settings to determine in what state they spawn?
I mean the spawn menu definitely needs an overhaul even with the filters it's just a mess, this could be a feature that could be implemented into that.
