 note = {application, This paper describes the measurement results of a normal joint gap and a singular joint gap of the rails using voltage detecting type rail joint gap sensor. In the case of a singular joint gap, the minimum value of a joint gap is able to be obtained by comparing the output voltage of two detecting coils that placed it toward the rail width and the measurement results of a normal joint gap.},
