The WAM-4 is an Indian locomotive. It was developed and built by the Indian manufacturer Chittaranjan Locomotive Works (for short: CLW) and the Research Design and Standards Organization (for short: RDSO) between 1970 and 1983, with 500 units produced. Its name is composed of W for wide gauge, A for alternating current, and M for mixed, indicating that it can be used for both freight and passenger trains, just like the Br 52 and the EMD. Finally, the 4 indicates that it is the 4th generation of the WAM series, similar to the EMD. She served with the Indian Railways for almost fifty years until she was retired between 2005 and 2020; nevertheless, she was one of the most successful Indian locomotives.
