WAP 5 is the name of a class of electric locomotive 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). Chittaranjan Locomotive Works (CLW) started production in 2000. It was designed to haul 18-coach passenger trains at 200 km/h (124 mph). It is the first 3-phase locomotive in India.

Other notable features of this locomotive are the provision of taps from the main transformers for Head end power (HEP or Hotel Load), pantry loads, flexible gear coupling and wheel-mounted disc brakes. Braking systems include 160 kN loco disc brakes, automatic train air brakes, and a charged spring parking brake.

The Bhopal Shatabdi hauled by a WAP-5 travels at 150 km/h (93 mph) in the New Delhi - Agra Cantt section. The service speed will be increased to 160 km/h from October.

Some of the units homed at Vadodara shed have air-conditioning. The production had been paused for a long time due to an indigenous replacement of the Hurth coupling. But now the production has resumed with the indigenous replacement.

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 100 mph.[1]

Sheds holding WAP-5[edit]

In addition to GZB shed till date, Vadodara electric loco shed is also given with new WAP5 locos from feb-2012 starting from 30044.No 30044 is named GAURAV.

Liveries[edit]

In recent time, 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.
