③If the railway switch can be operated in both fixed and reverse positions, there is no indication. Use a multimeter to AC 250V and measure whether there is an AC voltage of about 110V between X1 (or X2) and X3 on the distribution board. If there is voltage, it is an outdoor fault, otherwise it is an indoor fault. The inspection of rail joint bar bolts is divided into two types: manual and machine.
