COUPLING COMMAND CONTROLLER OF RAILROAD CAR

PROBLEM TO BE SOLVED: To couple and electric car an internal combustion railcar which has different performances and command systems without increasing the number of jumper wires between the electric car and the internal combustion railcar, and achieve the cost reduction and the improvement of maintainability. SOLUTION: Changeover switches 1D and 1E which are turned on at neutral positions and arrangement changeover switches 2D and 2E which can be changed in accordance with the type of a car to be coupled with are respectively provided on an internal combustion railcar and an electric car. Further, a detection relay 4 which detects an overhead feeder voltage is provided on the electric car side and an internal combustion railcar coupling confirmation signal circuit is provided on the internal combustion railcar side. In accordance with the type of a car to be coupled with, the control is practiced through jumper wires W1-W2 between the cars so as not to have a coupling command contactor closed unless coupling conditions are correctly established.
