Derailing a train

[Chappi]

Hello there, is it possible to actually derail the train locomotive? I've tried cutting of my train rails into a huge canion so the train should fall down but it simply doesen't. It's possible to push the train cars off the tracks, but the locomotive acts as if it hit an invisible wall and it can't derail itself. Is it possible to make it act like a train car and actually derail?
