ED4 (Electric train Demikhovskiy 4-th modification) is a series of Russian electric trainsets, in production since 1996. The trains are produced by DMZ and currently in service on RZD lines in almost every part of the country and former USSR states. ==Production history== The ED4 was designed to accommodate Russia's need for a domestically produced electric train-set. Russia's most widely exploited electric trains, the ER1 and ER2 series, were produced by the Rīgas Vagonbūves Rūpnīca (RVR) plant in Latvia before the collapse of the USSR. Design work began in 1996 on the basis of the earlier ED2 series, which were largely equipped with RVR components. Electronic equipment for the new train was manufactured by The Novocherkassk Electric Locomotive Plant, while the drive-train was built in Novosibirsk. ED4 train-cars are nearly identical to those used by both the ER29, and ED2T trains, differing mainly in having notably wider doors. After successfully completing testing, the first train entered service at the Mineralnye Vody Depot of the North Caucasus Railway. Only 5 trains carry the early ED4 identification, as the second variant, ED4M, began exclusive production thereafter. The main difference between the two trains is the equipment and shape of the operator's compartment.〔(Information about ED4 )〕 Four of the early ED4 trains are in currently in service on the Moscow Railway, one on the North Cacasus Railway, and one in Belgorod.〔(Service of ED4 in Russia )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「ED4 (Electric trainset)」の詳細全文を読む スポンサード リンク
