Ukrainian Armed Forces strike railway tracks in Kursk's Lgov, says mayor
According to Klemeshov, four arrivals were recorded in the city. Two residential buildings and the railway tracks of the Lgov-Kyiv station were damaged. There was also a fire in a warehouse of one of the city's factories. No residents were injured.
“I do not recommend that anyone who left the city return until the situation has finally stabilized,” the mayor wrote.
You could do it with a hacksaw, if you had enough replacement blades. And you could do it with an arsenal of bastard files as well. Each iteration on the idea takes considerably more time and effort, though. Those rails are quite a bit tougher than you might realize.
Yeah I know, railroad tracks are extremely hard steel. Just poking fun
Battery operated angle grinders are plentiful (noisy though).
Can you not use some form of explosive charge
