ER2 electric trainset is a DC electric multiple unit which was in production by the Railroad Machinery Plants of Riga (in consortium with the Electrical Machinery Plants of Riga and the Railroad Machinery Plants of Kalinin) from June 1962 to mid-1984. It was essentially an improvement of the ER1 design, featuring footboards for low platforms, and aprons for high platforms, as well as improved electrical equipment and minor changes to the bodywork (specifically, the engineer's cab, side walls, headstocks, and door mountings). Since the mid-1960s, the ER2 has been the most widely used type of suburban train in the Soviet Union and its successor states.
