Got tired of having this conversation over and over again so I just spent way too long making this:

In case anyone is wondering: yes, this is how train robberies operated in the Old West. Slip the switch after the locomotive passes by, passenger cars are stuck there. They could rob everyone and get away before the locomotive could even stop and reverse back to the passenger cars.

And in case you were also wondering: yes, this tactic is still used by people stealing UPS packages from trains in various American cities today.

The videos I've seen say that the thieves cut open the containers and make off with the contents at normal train stops.

Here's a longer video, showing derailed cars.

Cause of the derailment is unknown.

Possibly caused to facilitate theft?
The thieves do have bolt cutters, to open the containers. Could be used on the switch locks too.
