A locomotive or engine is a rail transport vehicle that provides the motive power for a train. If a locomotive is capable of carrying a payload, it is usually rather referred to as a multiple unit, motor coach, railcar or power car; the use of these self-propelled vehicles is increasingly common for passenger trains, but rare for freight trains.
A multiple-unit train or simply multiple unit (MU) is a self-propelled train composed of one or more carriages joined, which when coupled to another multiple unit can be controlled by a single driver, with multiple-unit train control.
A diesel locomotive is a type of railway locomotive in which the power source is a diesel engine. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. The most common are diesel-electric locomotives and diesel-hydraulic.
The UIC classification of locomotive axle arrangements, sometimes known as the German classification or German system, describes the wheel arrangement of locomotives, multiple units and trams. It is used in much of the world, notable exceptions being the United Kingdom, which uses a slightly simplified form of UIC, and in North America, where the AAR wheel arrangement system is used to describe diesel and electric locomotives. In North America, the Whyte notation is only used for steam locomotives.
Push–pull is a configuration for locomotive-hauled trains, allowing them to be driven from either end of the train, whether having a locomotive at each end or not.
B-B and Bo-Bo are the Association of American Railroads (AAR) and British classifications of wheel arrangement for railway locomotives with four axles in two individual bogies. They are equivalent to the B′B′ and Bo′Bo′ classifications in the UIC system. The arrangement of two, two-axled, bogies is a common wheel arrangement for modern electric and diesel locomotives.
The M62 is a Soviet-built diesel locomotive for heavy freight trains, exported to many Eastern Bloc countries as well as to Cuba, North Korea and Mongolia. Beside the single locomotive M62 also twin versions 2M62 and three-section versions 3M62 have been built. A total number of 7,164 single sections have been produced, which have been used to build 5,231 single-, twin- and three-section locomotives.
EU07 is the name for a Polish electric locomotive in service of the Polish railway operator PKP. This locomotive was designed as a mixed traffic locomotive, and as such is used both in freight and passenger traffic.
PKP class EP07 is a class of standard-gauge electric locomotives used primarily for passenger trains in Poland. They are rebuilt EU07 class locomotives, which in turn are the direct successors to the post-war British EU06 series locomotives. The only operators of this locomotive series are PKP Intercity and Polregio.
Originally, both Deutsche Bundesbahn and Deutsche Reichsbahn continued the classification system of the Deutsche Reichsbahn (DRG) – see also a short overview of the numbering system of the German railways. When UIC introduced a new classification system that could be processed by the computers of the late 1960s, DB did a major modification of their system, effective 1 January 1968. This system is still in use and now includes the engines of the former GDR railways as well.
The different railway companies in Germany have used various schemes to classify their rolling stock.
The PKP class Lyd2 is a narrow gauge diesel-hydraulic locomotive built by FAUR in Romania, for use initially for sugar cane railway in Egypt with later variants developed for use in Poland, Romania and Albania. It was commissioned by Polskie Koleje Państwowe for service on the railways of Poland.
This page explains the numbering and classification schemes for locomotives employed by the Japanese Government Railways, the Japanese National Railways and the Japan Railways Group.
SP32 is a Romanian series of diesel passenger locomotives used by PKP.
For more than a century, the Swiss locomotive, multiple unit, motor coach and railcar classification system, in either its original or updated forms, has been used to name and classify the rolling stock operated on the railways of Switzerland. It started out as a uniform system for the classification and naming of all rolling stock, powered and unpowered, but had been replaced and amended by the UIC classification of goods wagons.
The DRG locomotive classification system was developed by the German Imperial Railway Company or Deutsche Reichsbahn-Gesellschaft (DRG), which was formed in 1924 following the merger of the German state railways (Länderbahnen) in 1920. A common classification and numbering scheme was needed in order to organise effectively the four hundred or so different steam locomotive classes taken over from the state railways, as well as new locomotives. This process lasted until 1926. Only then was the final renumbering plan fixed.
The DR locomotive classification scheme in East Germany in the initial post-war period used the DRG system, consisting of a class number (Baureihennummer) followed by a serial number (Ordnungsnummer). With the introduction of computerised (EDP) numbers in 1970 as part of the UIC framework, the system was fundamentally changed for the first time.
EW51 was a three-car electric multiple unit, produced by the Lilpop, Rau i Loewenstein plants in Warsaw, H. Cegielski Spółka Akcyjna in Poznań and L. Zieleniewski in Sanok in the years 1936–1939. Electrical equipment was supplied by English Electric. The units were intended for suburban traffic in the Warsaw area. Before the war, the units had second- and third-class compartments. A total of 76 units were produced. Currently, the only surviving vehicle, EW51-36, is the property of the Museum Station in Warsaw. Restoration was completed in January 2019.
The PKP class Lyd1 is a narrow gauge diesel locomotive class, covering two similar models built in Poland: WLs150 built by Fablok, and its development WLs180 (803D) manufactured by Zastal. It was used by Polish State Railways (PKP) on the narrow gauge railways in Poland, and on industrial railways.
The WLs40 and WLs50 are narrow gauge diesel locomotives built in Poland, used mostly on industrial railways. A small number was used by Polish State Railways (PKP) as Ld1 class on narrow gauge railways in Poland.
