A method for locating a railway vehicle includes: measuring an acoustic signature of a railway vehicle passing over a railway switch for switching between a first railway track and a second railway track diverging from the first railway track, using a distributed acoustic sensing apparatus including an optical fiber sensor placed along the railway switch; analyzing the measured acoustic signature, using an electronic processing unit, by identifying, in the measured acoustic signature, vibration patterns representative of track geometry and/or track curvature; and determining which of the first railway track or the second railway track is occupied by the railway vehicle, using the electronic processing unit, based on the identified vibration patterns.
