The trains could be heavily guarded as well. Even in the US in the 20s Marines guarded mail cars with shotguns and tommy guns. They could also be found patroling backroads with cars and motorcycles with BARs.

In the warlord-torn China of the same time it was tommy guns, C96 Mausers/he zi pao and swords. You could look into warlord-era China as a sort of guide but there was a surprising amount of production of knock-offs of Western guns and railroad guards ate up a lot of it.
