Nowadays, It is a common locomotive used in freight trains. WAG-9 has quickly become one of the important locos in the Indian railways. With its higher power, this locomotive has replaced WAG-7 which was the main electric loco before WAG-9's arrival. Applications where twin WAG-7s were required are now handled by a single WAG-9. This includes both leading a long consist and for banking operations. The regenerative braking capabilities of WAG-9 has also helped reduce the electricity consumption. The original WAG-9 had some wheel slippage incidents while hauling heavy load. This was rectified through the introduction of WAG-9H and subsequently using WAG-9i.

Production of this class was halted in December 2015 with locomotive number 25051 being the last unit to be rolled out. As of September 2022, all locomotives except those lost in accidents still retain operational status on the mainline as WAP-4, with further examples having been converted from WAP-6. The WAP-4 class was developed after its predecessor, the WAP-1, was found inadequate to haul the longer, heavier express trains (24-26 coaches) that were becoming the mainstay of the Indian Railways network. The loco has a streamlined twin cab carbody design, with top-mounted headlamps. The first 150 or so units had the headlamp mounted at waist level, with the lights being mounted in a protruding nacelle.

Other notable features of this loco are the provision of taps from the main loco transformer for hotel load, pantry loads, flexible gear coupling, wheel-mounted disc brakes, and a potential for speed enhancement to 200 km/h (120 mph).
