Provided are a train traction cutting-out and control system and method in the case of emergency braking. When emergency braking is applied, coils of a first relay (K1) and a second relay (K2) are simultaneously powered off. An auxiliary contact of the first relay (K1) is opened, a traction pulse of a traction converter is blocked, and an output of a traction force of the traction converter is cut off, so that a traction cutting-out function is achieved, wherein the safety level of the traction cutting-out function is SIL2; in addition, an auxiliary contact of the second relay (K2) is opened, a coil of a contactor module is powered off, a main contact of the contactor module is opened, an input power source of a main circuit of the traction converter is opened, and an output of a traction force of the traction converter is cut off, so that a traction cutting-out function is achieved, wherein the safety level of the traction cutting-out function is SIL1. The traction cutting-out function of which the safety level is SIL2 and the traction cutting-out function of which the safety level is SIL1 are simultaneously achieved, so that the entire train achieves the safety requirements of the traction cutting-out level SIL3 in the case of emergency braking.
