Multiple units of India

A multiple-unit train or simply multiple unit (MU) is a self-propelled train composed of one or more carriages joined together, which when coupled to another multiple unit can be controlled by a single driver, with multiple-unit train control. Although multiple units consist of several carriages, single self-propelled carriages, such as railbuses and trams – are in fact multiple-units when two or more of them are working connected through multiple-unit train control.

In India, MUs are used for all suburban trains and metros and are increasingly used for short-medium-long distance trains also such as DEMUs, SSEMUs, MEMUs and Vande Bharat Express.
