Template:Infobox locomotive

The Indian locomotive class 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).

One of the notable features of WAP-5 is regenerative braking. 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 Template:Convert. Braking systems include Template:Convert 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 Template:Convert.[1]

The Gatimaan Express and Bhopal Shatabdi trains hauled by WAP-5 locomotives travel at Template:Convert and Template:Convert 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 for speed operations up to Template:Convert. The control software was also modified accordingly. Another locomotive (no. 30164) was rolled out with aerodynamic cab profile. This is just a trial and not intended for passenger use as the tracks are not supported in major routes.

Head-On Generation (HOG)

A WAP-5 locomotive (no. 30140) with Head-on Generation (HOG) was rolled by CLW in June 2018. In this locomotive, the hotel load converter has been accommodated in the same cubicle of traction converter. More locomotives of this type will be rolled out in future.

Power upgrade to 6000 HP

In March 2018, CLW rolled out a WAP-5 locomotive (no. 30136) with an enhanced power output of about Template:Convert. Modifications were carried out in the control software. Based on successful trials, the Indian Railways decided to proliferate the modification on all WAP-5 locomotives.

Tejas Express push-pull version

Two WAP-5 locomotives (no. 35012 and 35013) were given a single-cab design and an aerodynamic profile. One locomotive will be placed on each end of the train to utilize a push-pull configuration for future Tejas Express services. The two locomotives have a power output of Template:Convert and will have a maximum speed of Template:Convert. These locomotives were inaugurated in October 2020.[3]

Liveries

  • The most common livery for WAP-5 locomotives is white, black and a twin red band.
  • In 2014, Amul Milk made a contract with Vadodara Shed to apply wrap advertising on 20 Vadodara-based WAP-5 locomotives.
  • WAP-5 locomotives based at Electric Loco Shed, Ghaziabad have large P-5 decals on the sides.
  • Another wrap advertising for Fortune Edible Oils was released by Vadodara (BRC) Electric Loco Shed with locomotive no. 30081.
  • The Tejas WAP-5 with the same livery as the Tejas Express.
