My comment in nostr:npub1pumn9x5j9je56c6jxhyh6m7zhxuj3pgu5a8axva9t8c0sz8f8nhsg9a8vt about sabotage disrupting railways in Poland. Radio emission brings trains to a halt in several places. Who's behind unclear. Executing this sabotage is technically simple (I explain), though requires proximity. Solution: move to GSM-R.
