31234-WAG9i-GMO --- Earlier spotted in Aug'12 near Tamluk. This time Somsubhra Das framed this majestic rare breed of Gomoh ELS waiting with coal-filled BOXNA rakes at Mecheda on 17th March 2015. The WAG9i are variant with Insulated Gate Bipolar Transistor (IGBT) control. Two inverter assembled for each bogie, enabling per-axle isolation in the case of traction motor failure. If one traction motor fails, power supply to its axle gets cut-off leaving the loco with 5000hp on the other axles.
