Indian locomotive class WDM-3A
The class WDM-3A is Indian Railway’s workhorse diesel –electric locomotive. Since 1993, it has been manufactured in India by the Diesel Locomotive Works (DLW), Varanasi. The model name stands for broad gauge (W), diesel (D), mixed traffic (M) engine. The WDM-3A is the most common diesel locomotive of Indian Railways. The WDM-3A is a variant of the original WDM-2C. These units have been retro-fitted with dual brakes, in addition to the air and vacuum brakes. The WDM-3A locos have a maximum speed of 120 km/h (75 mph). The gear ratio is 65:18.
The loco is now widely used across India for long distance passenger trains due to its gentleness and high reactive loads and acceleration.
