History
The history of WAP-3 begins in the early 1980 with the WAP-1 class. The WAP-1 was the first attempt to create a dedicated High-speed electric passenger locomotive.[1] They were first used on the Howrah Rajdhani Express.[2] But Indian railways were not satisfied with the performance of the WAP-1 as they could haul around 19 coaches at a max speed of 120 km/h. So Indian Railways decided to procure a faster version of the WAP-1.[3]
The WAP-3 was ordered from CLW to the design of RDSO. The Flexicoil cast steel bogies of the WAP-1 was replaced by Flexicoil Mark II versions. This increased max speed to 140 km/h. Five prototype locomotives of this type were made from existing WAP-1 units. The first prototype WAP-1 numbered '22005 jawahar' was put into service in 1988. Initially these locomotives were classified as WAP-1 FM II[4] with FM II standing for " Flexicoil Mark II " and were certified to run at 130 km/h between Jhansi and lalitpur section.[5] Later Flexicoil Mark 4 bogies were provided for Subsequent WAP-3 which increased max speed to 160 km/h.
They were first used on the Taj Express and then various shatabdi express.[6][7] The Bhopal shatabdi used to run with WAP-3 for some time.[8] But as trains got longer the WAP-3 struggled to perform and required banking locomotives on moderately graded sections, and so did not meet their design goals these were reverted to WAP-1 class again.
The WAP-3 and WAP-1 provided the basis for the WAP-4 class.
