The WAG-5 is a type of electric locomotive used in India. It is the second most widely used locomotive on Indian railways, with a total of 1197 units built including variants.[1] WAG5A is the one with Alstom traction motors. WAG5B is a converted WAM4. WAG5H(x) is with Hitachi traction motors. WAG5P(x) is a passenger dedicated class. WAG5(x)D are fitted with dual brakes and WAG5(x)E are fitted with air brakes. WAG5RH are fitted with Rheostatic or Friction braking. The units with additional '6P' markings have all parallel grouped traction motors. Some units are fitted with Static Converter(STC), Microprocessor, Dynamic brake resistors(DBR), SI unit and Vigilance control device(VCD).
