The Western Railway operates Electric multiple units (EMUs) on the Western line of the Mumbai Suburban Railway, which forms part of the Ahmedabad–Mumbai main line. The EMUs ply between Churchgate and Virar (60 km) and is projected to extend the service till Dahanu Road (Services actually started on 16 April 2013), while mainline electrical multiple units (MEMUs) service the section beyond Virar till Dahanu Road (60 km). EMUs are of 12-car or 15-car rakes and are differentiated as slow and fast locals. Slow trains halt at all stations, while fast ones halt at important stations only and are preferable over longer distances. The first electric train on this section was introduced in 1928 between Churchgate and Andheri.
