ВЛ10У-795 d.c. electric locomotive of Russian railways
ВЛ10У-034 dc electric locomotive and ТЭМ8В-034 diesel switcher
VL10 3 kV DC two-section electric locomotive was designed in parallel with VL80 25 kV 50 Hz AC electric locomotive. The technical project of new two-section DC electric locomotive VL10 (ВЛ10; Т8) was developed by the special design bureau of the Tbilisi Electric Locomotive Plant (TEVZ) in Soviet Georgia under the direction of chief engineer G. I. Chirikadze by 1960. Even though the locomotive was initially named after design bureau of TEVZ - T10 it was later renamed in Soviet tradition but for the last time after the Bolshevik leader - Vladimir Lenin. VL80 AC electric locomotives were built by Novocherkassk Electric Locomotive Plant (NEVZ) according to the projects developed by the VELNII in Novocherkassk, Russia to 1961. Unified bogies of VL10 and VL80 locomotives were designed and built by NEVZ. Both took innovative 2-axle bogies with french-type wheelset's suspension by two diagonal link arms supported by the axlebox based on original ALSTOM design. The principle of suspension were taken from the French-built F series of Co-Co electric locomotive (Фк) built specially for the Soviet Railways and was firstly used in VL60 AC electric locomotive with 3-axle bogies developed by NEVZ. Traction motors TL-2 (ТЛ-2) with capacity of 650 kW (in hourly mode) each, have a support-axis suspension. Motor's frame, bearing plate, armature shaft, small gear, brush apparatus were made unified with motor НБ-412М of VL60 electric locomotive. VL10 locomotives were built from 1961 to 2005 by the Novocherkassk Electric Locomotive Plant in Russia and Tbilisi Electric Locomotive Works (TEVZ) in Soviet Georgia with total production 2900 ones. VL10U (ВЛ10У) was the last modification also designed by Tbilisi Electric Locomotive Plant - the locomotive were additionally weighted - the rail load increased from 23 to 25 t so the wheels have greater traction force, and be able to carry heavier trains. Mechanically, VL10U was unified with NEVZ-built AC electric locomotives VL80T, VL80S, VL80R. Two bogie traction rods were installed of two sides of doubled hydraulic damper located in center of bogie. The body, cabin, pneumatic and main equipment were unified with VL10, VL11, VL11M DC electric locomotives. Totally 979 electric locomotives VL10U were built.
