The invention provides a train trackside positioning and speed measuring system and method. The system comprises a 5G mobile terminal, a UWB tag, a 5G base station, a UWB base station, a radar, a 5G positioning server, an edge radar processor, a 1588 clock server and a central positioning server. Wherein the 5G mobile terminal and the UWB tag are vehicle-mounted equipment and are installed in a train; the 5G base station and the UWB base station are integrated base stations and are arranged beside a train track; the 5G positioning server is connected with the 5G base station and is arranged beside a train track; the radars are connected with the radar edge processor and are arranged in a turnout area and a platform area; the 1588 clock server is used for carrying out clock synchronization through a 1588 protocol; and the central positioning server is used for fusing the train data and positioning and measuring the speed of the train. According to the scheme provided by the invention, the method does not depend on vehicle-ground wireless communication, reduces the types and number of positioning devices, and solves the problems that a non-communication vehicle does not have continuous position tracking and is affected by idle slip.
