The embodiment of the invention provides a safety circuit for a railway vehicle and the railway vehicle. In the safety circuit, a one-position end driver controller occupies a normally open contact A1 and a movable contact A2 of a relay K01, and a coil of the one-position end driver controller A01, a normally closed contact A3 and a movable contact A2 of a non-emergency braking relay K05 and an FB position confirmation relay K03 is connected between a power supply positive electrode and a power supply negative electrode in series. A normally-closed contact A3 and a movable contact A2 of a group A of contacts of an FB position confirmation relay K03, a normally-closed contact A3 and a movable contact A2 of a group A of contacts of an emergency braking trigger condition indicating device K06, a coil of a non-emergency braking relay K05, a normally-closed contact B3 and a movable contact B2 of a group B of contacts of an emergency braking trigger condition indicating device K06 and a normally-closed contact A3 and a movable contact A2 of a group B of contacts of an FB position confirmation relay K03. And a normally closed contact B3 and a movable contact B2 of the B group of contacts of the FB position confirmation relay K03 are connected in series between the power supply positive electrode and the power supply negative electrode. According to the embodiment of the invention, the technical problem of potential safety hazards caused by automatic re-establishment of a traditional safety circuit is solved.
