The invention relates to a GNSS and electronic map topological structure-based train positioning system and a method. The train positioning system comprises a GNSS satellite positioning receiver module, a Kalman filter module, a map matching algorithm module and a vehicle-mounted electronic map module. The GNSS satellite positioning receiver module is connected with the map matching algorithm module through the Kalman filter module, and the map matching algorithm module is connected with the vehicle-mounted electronic map module; and the map matching algorithm module accurately matches the train positioning data output by the Kalman filter module to a certain track segment in an electronic map of the vehicle-mounted electronic map module, so that accurate positioning of the train is realized. Compared with the prior art, the method has the advantages that the dependence of a positioning algorithm on ground equipment is reduced, and the construction cost and the manpower maintenance cost of local railways are reduced.
