To provide an electronic train detector control section length measuring device which requires less manpower for measuring works.SOLUTION: An electronic train detector control section length measuring device comprises current measuring means to measure a current value made to flow from an electronic train detector to rails and arithmetic processing means to calculate a control section length using a current wave form. The arithmetic processing means comprises extreme value point extracting means, pass time calculating means, a train speed calculating part and a control section length calculating part. The extreme value point extracting means extracts extreme value points of measured current values. The pass time calculating means calculates times from a start point and an end point of a control section to their nearest extreme value points, a time from the first extreme value point to the second extreme value point and a time from the last extreme value point to an extreme value point, one extreme value point's pitch before the last extreme value point. The train speed calculating part calculates a train approaching speed using a time from the first to the second extreme value points and a vehicle wheelbase length and a train going away speed using a time from the last extreme value point to an extreme value point, one extreme value point's pitch before the last one and a vehicle wheelbase length. The control section length calculation part calculates a length of a control section using the train approach speed and a time to the first extreme value point and using the train going away speed and a time from the last extreme value point.SELECTED DRAWING: Figure 2
