I can't find the story, but years ago I read an article where they relayed a story from a miner encampment around that same time period. During that time they went on strike and the miners expected the company would run another armored train through their encampment. So a bunch of them walked about a mile up the tracks, pulled up the rails and rolled them down an embankment so when the train came through, it couldn't continue to the encampment for the attack, and the rails were too heavy for the mercenaries to bring back up the hill. I'll keep trying to find it though. It was an interesting read.
