configurations at different power settings. At notches up to 14, all motors were in series (at notch 14 all resistors dropping out); up to notch 21 in series-parallel combinations (three pairs of motors in series, the pairs themselves being in parallel); and further notches with all motors in parallel (at notch 30 all motors are in parallel with resistors dropping out). This is the original configuration of the WCAM-1 series of locomotives too.

which was the Alstom made TAO TM. A single WAM-4 can generally haul up to a 24-coach passenger rake. This class proved so successful by virtue of its ruggedness suitable for Indian conditions and simplicity of maintenance. In January 2020, the last WAM-4 units (four from Tata ELS) were withdrawn from mainline service. Currently 8 locomotives (including 1 WAS-4) are doing shunting and departmental works.

better for the mixed traffic loads especially as it allowed the locomotives to start hauling larger loads without stalling. With increasing use of the WAM-4 locomotives for passenger traffic the all-parallel configuration was deemed more desirable since it allowed higher speeds and higher acceleration.

Production of these locomotives started in 1970 with #20400 and exactly 500 WAM-4s were built in 13 years with #21399 “Anant” being the last one. Production ended on August 3 1983. WAM-4 though an indigenously produced loco was heavily inspired by French box design and naturally favoured a French TM

The WAM-4 locomotives were later reconfigured to have all motors always in parallel (6P variants) or with the three series-connected pairs in parallel (2S 3P variants). Some WAM-4 locomotives from CLW are thought to have had the 2S 3P configuration right from the start. The 2S 3P configuration was

The 'DB' or 'D' generally, but perhaps not always, indicates dual-brake capability. 'HS' may be for 'high speed'.'2S', '3P', '6P', etc. indicate traction motors connected in series or parallel. The WAM-4 has six traction motors, and originally they were wired to be available in different

The class was designed for both passenger and freight work. Many of the original locomotives were fitted with vacuum brakes only. With the withdrawal of many WAG-1 and WAM-1 locomotives in the 1990s, the WAM-4 units were given air brakes to prolong their life into the 1990s and beyond.
1022:
A number of locomotives were rebuilt as WAM-4B in the late 1970s to evaluate Alstom TAO 659 Traction Motors and for exclusive use on freight duties. These 'locos' were ballasted to improve traction and had excellent load-hauling capabilities, This experiment gave rise to the future

This loco class has been seen in many variations, as a lot of workshops and sheds have carried out their own enhancements or modifications to the basic loco design. Although the code indicates a mixed-use loco, most WAM-4's ended up hauling passenger trains.

The WAM-4 is one of the most successful locomotives of Indian Railways having served both passenger and freight trains for over 52 years. This class provided the basic design for a number of other locomotives like

As increasing numbers of WAM-4 have been retired, some have found their way into museums or other uses. A few WAM-4 locomotives have been preserved by Indian Railways at various location around India.
2040: 2665: 2021: 849:, the WAM-4 locomotives were relegated to hauling smaller passenger trains and most of the units have been scrapped. A few units are in service performing backup and non-essential duties. 2094: 1994: 2060: 3524: 276: 3514: 2006: 2658: 1730: 1681: 1071: 889: 55: 1216: 977: 174: 2651: 581:
