The locomotives of the class ВЛ8 (German transcription WL8) of the Soviet Railways (SŽD) are wide - gauge double locomotives for operation with 3 kV direct current . Originally designated as the class Н8 (German: N8) introduced received this only in 1963 its current name, the abbreviation BЛ (WL) for the initials of first and last name Vladimir Ilyich Lenin stands.
Series ВЛ8 / Н8
In order to create a more economical alternative to double units of the ВЛ22М series in freight transport, the Novocherkassk electric locomotive factory began developing the first Soviet double locomotive for electric operation in 1952 , similar to the two-part ТЭ2 diesel locomotive developed a few years earlier . The technology was largely based on the ВЛ22 series , the first electric locomotive built in large numbers in Novocherkassk. The two halves of the locomotive received only four axles instead of six, as they are arranged under the one-piece box on the ВЛ22. The prototype known as the Н8-001 was completed in 1953. The series designation Н8 was derived from the Novocherkassk plant location (Новочеркасск) and the number of axles.
The two halves of the locomotive were firmly connected to each other and were only separated for maintenance. The locomotive body was redesigned compared to the series ВЛ22 with side-mounted driver's cab doors in contrast to the ВЛ22, in which the driver's cab door is in the front. The Н8-001 was equipped with newly designed engines of the type НБ-406А (German: NB-406A).
The prototype N8-001 was tested on the Tbilisi - Sestaponi and Kropachovo - Zlatoust - Chelyabinsk routes . In 1955 the N8-002 to -008 were built, in 1956 the series production of the N8 series began.
From 1957, the locomotive bodies were supplied by the Luhansk locomotive factory . From 1958, the Tbilisi electric locomotive factory was included in the construction of the N8 series for reasons of capacity . The locomotives built there received a changed company symbol on the front, and instead of the star, the abbreviated name of the plant was also given in Georgian script . From January 1963, the series designation ВЛ8 was used, the locomotives delivered up to then were renumbered. In Novocherkassk, ВЛ8-001 to -200 and -1201 to 1431, in Tbilisi ВЛ8-201 to 1200 and -1432 to 1723. For the last series from Tbilisi, the design of the company symbol on the front has been changed. The construction of the ВЛ8 ended in 1967. Production was completely converted to the successor series ВЛ10 .
From the mid-1970s, the ВЛ8 were increasingly used in passenger transport and equipped with heating cables for this purpose .
From 1956 a one-piece six-axle version was built in Novocherkassk as the ВЛ23 series .
ВЛ8В series
The ВЛ8В-001 was built as a one-off in 1966 at the Tbilisi electric locomotive factory. It also received the equipment for use with 6 kV direct current. It was retired in 1976.
ВЛ8М series
The maximum speed of the ВЛ8 is 80 km / h. To increase the speed, ВЛ8-948 was modified in 1968, but the top speed could only be increased to 90 km / h. It was not until 1973 that the ВЛ8-321 was converted for a top speed of 100 km / h. From 1976 to 1985 more ВЛ8s were converted and have been referred to as ВЛ8М since then. Externally, they can also be recognized by the changed headlights. In 2007 at least the ВЛ8-599 was converted into the ВЛ8M-599 at the Lviv plant in Ukraine .
commitment
The series ВЛ8 was initially used on newly electrified Siberian routes. From 1967 it was replaced there by the successor series ВЛ10 and widely distributed in the network. When the Soviet Union dissolved in 1991, the ВЛ8 came to the railways of the successor states: to the RŽD in Russia , the UZ in the Ukraine, the GR in Georgia , the HJ in Armenia and the ADDY in Azerbaijan . In Russia, the ВЛ8s are out of service, they were last in service on the Black Sea coast from the Tuapse depot . In 2007, VL8 were still in operation in the Ukraine at Donetska Salisnyzja and until at least 2010 also at Prydniprowska Salisnyzja . In Azerbaijan, Armenia and Georgia, the locomotives are still in use in small numbers.
