The invention relates to the technical field of railway vehicles, and provides a trailer bogie and a railway vehicle, and the trailer bogie comprises a framework and a wheel set system. The framework comprises a bearing body and two plate springs, a center pin channel is formed in the middle of the bearing body, two installation channels are formed in the bearing body in the longitudinal direction of the framework, and the two plate springs are installed in the two installation channels respectively. The wheel set system comprises a shaft core, a shaft sleeve and two wheels, the shaft core is rotationally installed in the shaft sleeve, the two wheels are installed at the two ends of the shaft sleeve through bearings respectively, the two wheels are connected with the two ends of the shaft core through flexible plates respectively, a brake mechanism is constructed on the shaft sleeve, and the brake mechanism is arranged on the shaft sleeve. And the brake mechanism is in transmission connection with the shaft core and is used for driving the shaft core to brake. And the bearing main body and the plate spring replace the original cross beam and side beam structure, so that the lightweight effect of the framework is obvious.
