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 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.

Sheds holding WAP-5
Ghaziabad / GZB loco shed (Zone: NR) holds 93 WAP-5 locomotives.
Vadodara / BRC loco shed (Zone: WR) holds 68 WAP-5 locomotives.[3]
Named Locos
- WAP-5 30011 Navodit
- WAP-5 30012 Navjagran
- WAP-5 30013 Navkirti
- WAP-5 30015 Vijay Utkarsh

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 200 km/h (120 mph). The control software was also modified accordingly.
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. 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.
Enhancement in Power
In March 2018, CLW rolled out a WAP-5 locomotive (no. 30136) with an enhanced power output of about 4500 kW (about 6000 HP). Modifications were carried out in the control software including a parametric change to redefine the torque-speed characteristics of the locomotive.
Based on successful trials carried out in September 2018, I.Rlys decided to proliferate the modification in all WAP5 locomotives.
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.
