Abstract
A method using the position data being determined on the train to determine characteristics of the train and/or the track. This is achieved by providing position determining devices at two or more spaced locations along the train. The position of the two locations are determined by the position determining devices. A processor determines the difference between the two locations from the positions determined by the position determining devices and determines the characteristics of the train from the determined difference between the two locations.
Claims4
A method of determining location of a train having rail vehicles on a track, the method comprising:
- determining a first position of a portion of the train prior to or at a switch in the track;
- determining a second position of a portion of the train after the switch in the track;
- comparing the determined first and second positions to a data base on the train;
- and
- determining which branch track the train is on from a comparison of the positions to the data base.
