WAP 5 is the name of a class of "High Speed" electric locomotives produced and used by Indian Railways. The first 10 locomotives were imported from ABB in Switzerland in 1995. They are supposed to be a variant of the Swiss Lok 2000 (Design concept) and German DB Class 120 (mechanical chassis).

WAP-5 can deliver 6,000 hp (4,500 kW) at peak and has regenerative braking as one of its notable features. 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). Braking systems include 160 kN (36,000 lbf) regenerative brakes, loco disc brakes, automatic train air brakes, and a charged spring parking brake.

On 3 July 2014, a WAP-5 set an Indian speed record by hauling a train from Delhi to Agra within 90 minutes at a speed of 160 km/h (99 mph).[2]

The Gatimaan Express and Bhopal Shatabdi trains hauled by WAP-5 locomotives travel at 160 km/h (99 mph) and 150 km/h (93 mph) respectively in the New Delhi - Agra Cantt section.

200 km/h Variant

In October 2015, Chittaranjan Locomotive Works rolled out a WAP-5 locomotive (no. 30086) with a gear ratio of 59:35:19 and modified application software for speed operations up to 200 km/h (120 mph).

Another locomotive (no. 30164) will be rolled out soon with aerodynamic cab profile.

Head on Generation

A WAP-5 locomotive (loco no. 30140) with head-on generation (HOG) was rolled by CLW in June 2018.

Liveries

  • Common livery for WAP-5 locomotives is white, with 2 red stripes.
  • Recently, Vadodara Shed and Amul Milk made a contract of advertising 20 locomotives of Shed. Thus the Amul livery came into existence. The livery has the sides of locomotive painted in Amul livery. All the recent locomotives are being painted in this livery as part of contract.
  • WAP-5 locomotives homed at Ghaziabad loco shed have large 'P-5' decals on their body sides.
