Electric locomotive of ChS2 (Factory denotations - 25Ео, 34Е is a main passenger electric locomotive of direct-current, built on factories Shkoda from 1958 to 1973 for the railways of Soviet Union.

First experimental electric locomotives of ChS2

In 1958 factories Shkoda built four шестиосных electric locomotive of direct-current with the hauling engines of AL-4846zT by sentinel power 586 kW, that with the same as Chs1 applied on an electric locomotive. Two electric locomotives having a transmission relation of hauling transmission 1,951 (factory series of electric locomotive 25E0) targeted at the USSR. These electric locomotives, marked as ChS2-001 and ChS2-002 in December, 1958.

Known alterations of electric locomotives

On the base of electric locomotives of ChS2-540 and ChS2-549 were A-ChS2-540 and A-ChS2-549 is made with a passenger salon for transportation of engineering and commanding composition of railways at inspection journeys. On being in 2004 this электромотриса was in the depot of Moskva-kurskaya. A-ChS2 is done at the Zaporozhia электровозоремонтном plant to order of OAO «RZHD» as a self-propelled transport vehicle for transportation of workers of railway of different grade in the passenger salon equipped in place of engine-room. Booth of эаменена on new, on the type of booth of electric locomotive of Chs7. Elektromotrisa A-chs2-552, added to TCH-6 Moskva-sortirovochnaya by Moscow is also known. d.

The Yaroslavl электровозоремонтный factory conducts deep modernization of electric locomotives of series of 53E, the program of modernization of 34E is not developed, in addition, it is inadvisable from large age of electric locomotives. In the process of modernization a basket, электроаппараты (on the vehicles of electric locomotives of Vl10, Vl11), is replaced, old мотор-компрессоры is replaced new VU-3,5. In a power chart in place of group comptrollers of switching execute individual contactors, guided the microsystem of management a locomotive (MSUL). The renewed electric locomotive is got by denotation of ChS2K.

Similarly the Yaroslavl elektrovozoremontnyi factory conducts modernization on a project ChR2K-E, at which an electric locomotive in place of the system of MSUL is equipped the single system of autoconduct and management a hauling drive (ESAUP).

The Zaporozhia elektrovozoremontnyi factory also modernizes Chs2 with replacement of basket, but abandons here former chart, machines and vehicles.

In a depot burial Mound is also present ChS2-053 done in a электромотрису electric locomotive. At alteration an original basket is stored.
