Withdrawn from service and all except one scrapped
The Indian locomotive class WAM-1 was a class of 25 kVACelectric locomotives that was developed in the late 1950s by the Groupement 50Hz (a consortium of European locomotive manufacturers) for Indian Railways. The model name stands for broad gauge (W), AC Current (A), Mixed traffic (M) locomotive, 1st generation (1). They entered service in 1960, thus making them the first AC electric locomotives to be in service in India. A total of 100 WAM-1s were built by the European consortium between 1959 and 1961, which made them the most numerous class of mainline electric locomotive until the WAG-1.[1][2]
The WAM-1 served both passenger and freight trains for over 40 years. This class, though initially not a great success, provided the basic design for the WAM-4, which a number of other locomotives are based upon. However, with the advent of new 3-phase locomotives like the WAP-5 and WAP-7,[original research?] the aging fleet of WAM-1 locomotives were relegated to freight and shunting duties, with all of them eventually being withdrawn from service. The single surviving unit named 'Jagjivan Ram' has been preserved at the Kolkata Rail Museum in Howrah.
