The VL19 ( Cyrillic script : ВЛ19) was the first class of electric locomotives designed in the Soviet Union . Earlier classes had been designed in the United States and Italy . The VL19s were produced from 1932 to 1938 and became the main freight and passenger DC electric locomotives in the Soviet Union. They were built for 1,500 volt DC but some were later converted to dual voltage. The designation VL was in honour of Vladimir Lenin and "19" Indicates a 19-ton axle load.
6-418: The locomotives had a Co-Co wheel arrangement and there were six 340 kW traction motors giving a total output of 2,040 kW. The gear ratio was 3.74:1 and the wheels were 48 inch diameter. Following the introduction of 3,000 volt DC electrification, some locomotives were converted to dual voltage, 1,500 or 3,000 volt DC. Two locomotives have been preserved: This electric locomotive-related article
12-559: A different use (often with only some being actually "driven"). Modern diesel and electric locomotives are much more uniform, usually with all axles driven. The main notations are the Whyte notation (based on counting the wheels), the AAR wheel arrangement notation (based on counting either the axles or the bogies ), and the UIC classification of locomotive axle arrangements (based on counting either
18-427: A locomotive by type, position, and connections, with the adopted notations varying by country. Within a given country, different notations may also be employed for different kinds of locomotives, such as steam , electric , and diesel powered. Especially in steam days, wheel arrangement was an important attribute of a locomotive because there were many different types of layout adopted, each wheel being optimised for

Wheel arrangement In rail transport , a wheel arrangement or wheel configuration is a system of classifying the way in which wheels are distributed under a locomotive . Several notations exist to describe the wheel assemblies of
30-711: The UIC classification scheme is generally used for all locomotive types including steam, with some exceptions. In France , the UIC classification is used for diesels and electrics while a scheme similar to the Whyte notation, but counting axles instead of wheels, is used for steam locomotives. Notably, Switzerland had its own separate notation system until 1989, with the Swiss locomotive and railcar classification now only retained for its narrow gauge railways . Geared steam locomotives such as Shays , Heislers , and Climaxes do not have
36-665: The axles or the bogies). Whyte notation is generally used for steam locomotives throughout the United States , Canada , the United Kingdom and Ireland . For diesels and electrics, North America uses the AAR wheel arrangement scheme while British practice uses a slightly simplified form of the European UIC classification scheme (except for small diesel shunters, where Whyte notation is used). In mainland Europe ,
