The Indian locomotive class WAP-6 was a class of 25 kV AC electric locomotives that was developed in the mid-1990s by Chittaranjan Locomotive Works for Indian Railways. The model name stands for broad gauge (W), AC Current (A), Passenger traffic (P) locomotive, 6th generation (6). They entered service in April 1996. A total of 17 WAP-6 units were built at CLW between 1995 and 1998.

The WAP-6 were intended to be a higher-speed variant of the WAP-4, but were restricted to a top speed of 105 km/h after failing trials. All were based at Asansol (ASN) shed, but after conversion to WAP-4 specifications, they were reallocated to Howrah (HWH) shed.

History
This class was a regeared variant of the WAP-4 mounted on Fabricated Flexicoil Mark IV bogies, instead of the standard Co-Co Flexicoil Mark 1 cast bogies seen on other WAP-4 locomotives. All other specifications were same as WAP-4. WAP-1 no.22212 was the first to be rebuilt into a WAP-6, being fitted with Flexicoil bogies and other upgrades; it was later rebuilt into a WAP-4. Subsequently, 16 more WAP-1 units were re-geared and mounted on Flexicoil Mark IV high-adhesion bogies, which are similar to high-adhesion bogies made by ALCO. Renumbered to 22400–22416, they were intended for 160 km/h (99 mph) operations, but in trials, they were unable to reach that speed and were therefore restricted to 105 km/h (65 mph). Two units, 22406 and 22408, were upgraded with better wheel-sets. This class was unsuccessful,[according to whom?] with most locomotives of this series being converted back as WAP-4.[2]
