Currently, there are many gaps in the research on safety of hydrogen-powered trains, and hazardous points vary across different scenarios. It is necessary to conduct analysis for various scenarios order develop effective accident response strategies. Considering implementation hydrogen power rail transport sector, this paper reviews development status trains leak hazard chain. Based literature industry data, a thorough conducted challenges faced by scenario electrified railways, tunnels, train stations, refueling garages. Existing railway facilities not ready deal with accidental leakage, promotion needs be cautious.
