ED4 (Electric train Demikhovskiy 4-th modification) are 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

ED4-0001

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. [1]

Four of the early ED4 trains are in currently in service on the Moscow Railway, one on the North Caucasian Railway, and one in Belgorod. [2]

ED4MKM-AERO

Mechanically almost identical to the ED4MKM, these trains have an updated interior, modified for the needs of airport commuters. The AERO trains are in service in Moscow and St.Petersburg, serving the Domodedovo, Vnukovo, Sheremtyevo and Pulkovo airports, respectively. The modified door mechanisms of the AERO were used on all later ED4M trains. [3]

The plant's management decided to base the new electric locomotives on the ChS1 class of locomotive. Therefore, the more powerful AL4846eT traction motors and traction drive were installed in the experimental ChS1 locomotive. Thus, the ChS3 design was an improved version of the ChS1.

<span class="mw-page-title-main">Soviet locomotive class P36</span>

The Soviet locomotive class P36 was a Soviet mainline passenger steam locomotive type. Between 1950 and 1956, 251 locomotives were built. The locomotives were nicknamed "Generals" because of the red stripe down the side. The P36 had the same power as a class IS locomotive but the axle loading of 18 tons allowed its use on the vast majority of Russian railway lines, replacing class Su 2-6-2s and significantly increasing the weight of passenger trains. The P36 was the last type of mainline steam locomotive built in the Russian SFSR and the last one built, P36-0251, was the last steam locomotive produced by Kolomna Works, Russian SFSR. Though sometimes described as the "Victory" type locomotive, that nick-name actually belongs to the class L 2-10-0 built between 1945 and 1947.
