It is an object of the present disclosure to provide a technology with which a position of a car can be accurately estimated. A typical one of position estimation systems of the present disclosure includes: a railway track information storage unit that stores a railway track information database containing a railway track shape at each spot in a railway track; a railway track shape measurement unit that, in a train running on the railway track, measures a railway track shape at least twice; a position measurement unit that measures a position of the train on a railway track; a section determination unit that determines a collation section in the railway track information database based on a position measured by the position measurement unit; and a railway track information collation unit that, in the collation section, collates a DB railway track shape, which is a railway track shape contained in the railway track information data base, with a measured railway track shape, which is a railway track shape measured by the railway track shape measurement unit and estimates a spot on the railway track corresponding to the collated railway track shape as a position of the train on a railway track.
