How am I supposed to know? But we have 50-yr-old trains transporting toxic materials on 100-yr-old tracks. How often are tracks inspected and maintained? We can start there.
Tracks are inspected and serviced annually using a continuous inspection schedule by most railroads. Switching equipment is maintained on a continuous basis by either a switchman or a yard operator. Signaling equipment is checked as each train passes them and otherwise continuously maintained as needed. Rolling stock is checked in the yard as each train is assembled.
Notable exceptions are rapid transit systems run by the government.
