GPS Based Positive Train Control: Developments and Field Trials

A. Lissner, N. Kloss

Abstract:	In order to gain an initial insight on the applicability of satellite navigation technology for train traffic control, Kayser-Threde and the German Railways (Deutsche Bahn AG) performed extensive DGPS train tracking trials in September 1995. The tests were performed on a railroad section with a diesel locomotive and an electric locomotive under different speeds within 60 and 200 km/h. In the middle of the railroad section a reference station was installed in order to broadcast DGPS correction data. At four power masts along the track, light barriers were installed in order to synchronize the exact position output at four fixed points; this was used to analyze position repeatability. The paper describes in detail the following topics: a) equipment employed in the field trials, b) results of the field trials: position and velocity accuracy, reliability and continuity, c) current developments tailored to railway traffic control.
