POSSIBILITIES OF TRACTION AUTOMATION

The development of an automatic train control system, begun in 1969, on three motor coaches in the southeastern suburbs of Paris, is described. The equipment consists of the following: an imposed-speed device; a device for automatic stopping in stations; a speed limit programmer; a timetable programmer. The way of using this equipment, mounted in the driver's cab, and the conditions under which the driver can override the automatic control are explained. With an improved version of the system an accuracy of the time of arrival at a station (vs schedule) of about 6 sec was obtained, to the extent that late running from the preceding station did not exceed the possibilities of traction. Otherwise, several intervals between stations would be necessary in order to revert to the timetable. Measurements of the consumption of energy have enabled the saving in tractive power to be estimated at 15%.
