This is obviously satire, but I could see them trying to derail a train or two in order to stop rail traffic across the country.
Except they’d probably have to leave the city limits to really disrupt cross-country rail traffic...
Antifa already has. Two years ago, up near Tacoma, some Evergreen State students tried to use quick dry cement on the main north south line.

This is when I started considering, seriously, whether Democrats should absolutely be allowed to survive...
We have had a couple of derailed trains in the past few months which were interesting.
Personally, after some conversation and certain efforts carried out by their local authorities, I suspect the recent Tempe, AZ derailment may well have been such a case.
