A method for safely determining a position information of a train (58) on a track, wherein an on-board system (1) of the train (58) identifies trackside structures, is characterized in that the trackside structures comprise passive trackside structures (56, 56a-56e) which are passive in their identification by the on-board system (1), wherein the on-board system (1) determines appearance characteristics, current distances (93) relative to the train (58) and current angular positions (94, 95) relative to the train (58) of the passive trackside structures (56, 56a-56e) by means of a first sensor arrangement (60) of a first localization stage (50) of the on-board system (1), wherein the on-board system (1) stores a map data base (10) in which georeferenced locations (100) and appearance characteristics of the passive trackside structures (56, 56a-56e) are registered,wherein the first localization stage (50) allocates (14; 29, 28) passive trackside structures (56, 56a-56e) measured by the first sensor arrangement (60) to passive trackside structures (56, 56a-56e) registered in the map data base (10) using the determined appearance characteristics and the registered appearance characteristics, that a first position information (52) about the train (58) is derived (14; 30) from a comparison of determined current distances (93) and current angular positions (94, 95) and the registered locations (100) of allocated passive trackside structures (56, 56a-56e) by the first localization stage (50),that a second position information (54) about the train (58) is derived from satellite signals determined by a second sensor arrangement (61) of a second localization stage (51) of the on-board system (1),and that the first position information (52) and the second position information (54) undergo a data fusion (19), resulting in a consolidated position information (55) about the train (58). The inventive method allows determining a position information of a train, which is less cumbersome and less expensive in installation and operation, however provides and equivalent level of safety compared to state of the art train positioning methods.
