The wheel burns are real. Not sure if they are the same incident but the Southern railroad in US had an incident when a remote controlled mid train unit (unmanned) lost radio signal and the unit was left stuck in power so when the train stopped this unit kept powering but it couldn't move the train on its own. So it sat there spinning its wheels and digging huge holes in the rails like in the photo here.
Mate, if that loco pulls as hard as you do, it'd move anything.
I'd still rather have an ALCo.
