The Indian locomotive class WAP-3 was a class of 25 kV AC electric locomotives that was designed by Research Design and Standards Organisation (RDSO) and Chittaranjan Locomotive Works (CLW) for Indian Railways in 1987. The model name stands for Broad gauge (W), AC Current (A), Passenger traffic (P) locomotive, 3rd generation (3). They entered service in 1988. They were the faster variant of the previous WAP-1 class. A total of 9 WAP-3 were converted from existing WAP-1 units at CLW between 1987 and 1988, but were later reverted back to WAP-1 specifications.
