. WAG-5H(x) is with Hitachi traction motors. WAG-5P(x) is a passenger dedicated class. WAG-5(x)D are fitted with dual brakes and WAG-5(x)E are fitted with air brakes. WAG-5RH and WAG-5HR are fitted with Rheostatic or Friction braking. Another variant is WAG-5HG. The units with additional '6P' markings have all parallel grouped traction motors. WAG-5HB is built by BHEL. Some units are fitted with Static Converter(STC), Microprocessor, Dynamic brake resistors(DBR) and SI unit. Due to the advent of WAG-7 and WAG-9, these locos except WAG-5HA/HB are even used for passenger trains although it is a freight-dedicated locomotive. WAG-5HB is homed at Jhansi shed near BHEL's installations for maintenance purposes. WAG-5 has a shell of the WAM-4. Units numbered till 23293 have side Louvre and round glass windows like the WAM-4 and units after 23293 have WAG-7 style of Louvre for better ventilation.
