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. 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 at within 90 minutes at a speed of 160 km/h or 99 mph.[1]

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.

Sheds holding WAP-5[edit]

Named Locos[edit]

  • WAP-5 30011 Navodit
  • WAP-5 30012 Navjagran
  • WAP-5 30013 Navkirti
  • WAP-5 30015 Vijay Utkarsh
  • WAP-5 30044 Gaurav

Air Conditioning[edit]

The original design called for these locos to have air-conditioned cabs. This, however, has been dogged by controversy over costs and fitment, and the first units made by CLW do not have air-conditioned cabs. One of the ABB units, No. 30000, does have air-conditioning, fitted by the Ghaziabad shed as an experiment.

However, many locomotives now have air-conditioning for the comfort of the loco pilots.

Hurth Coupling[edit]

After the first four were built, there seemed to be a pause in the manufacture of this class at CLW. A problem with the Hurth coupling its indigenous replacement seem to have been part of the delay, but the locally manufactured components passed trials and production resumed.

However, the Hurth Couplings are being replaced by Alternate Drive Gear Assemblies in the newer locos. Hurth coupling has a rubber membrane where as Alternate Drive Gear system has combined curved tooth coupling/ring disc coupling, having no rubber membrane. First locomotive with alternate drive gear system for 160 km/h service speed (no. 30056) was dispatched to ELS/Vadodara in December 2012.[3]

200 km/h Variant[edit]

In October 2015, Chittaranjan Locomotive Works rolled out a WAP-5 locomotive (loco number 30086) with Alternate Drive Gear Assembly and gear ratio changed to 59:35:19, along with changes in application software. This loco is suitable for 200 km/h operations, with a maximum speed of 225 km/h.

Head on Generation[edit]

A WAP-5 locomotive with head-on generation (HOG) is currently under development at CLW.

Liveries[edit]

  • 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.
