Locomotives Locomotives The 1922 Locomotive Cyclopedia of American Practice, published by Simmons-Boardman, is the most recent Locomotive Cyclopedia to be in the public domain. At 1141 pages of main text, plus indexes, front matter, and other content, it is a substantially sized book. It is basically a combined catalog for all the major builders of railroad locomotives and associated equipment in North America. It contains photographs and scale drawings of several hundred locomotive types as examples of the locomotives that North American builders can produce, as well as chapters on all manner of locomotive components, appliances and equipment, with material provided by the major builders of such. ...more on Wikipedia about "1922 Locomotive Cyclopedia of American Practice"
At the end of the 1960s, British Railways adopted the Total Operations Processing System (TOPS), a computerised system developed by the Southern Pacific Railroad in the United States. All types of locomotive and multiple unit received a TOPS classification, but the first attempt at applying TOPS was soon modified. This page explains the first attempt at using TOPS and cross-refers the classes allocated with those adopted in the successful re-arrangement. An explanation of the final arrangements for TOPS classification may be found here. ...more on Wikipedia about "British Rail TOPS first arrangement"
An Electro-diesel locomotive is a special type of locomotive that can be powered either from an external electricity supply (i.e. as an electric locomotive) or from an onboard diesel engine. Typically, they are more powerful when operating from an electric supply, since due to space constraints the diesel engine is small and therefore generates less power. ...more on Wikipedia about "Electro-diesel locomotive"
A fireless locomotive was a type of locomotive designed for use under conditions restricted by either the presence of flammable material or the need for cleanliness. Thus a traditional steam locomotive is ruled out because of its open fire. ...more on Wikipedia about "Fireless locomotive"
A gas turbine-electric locomotive, or GTEL, is a locomotive that uses a gas turbine to drive an electric generator or alternator. The electric current thus produced is used to power traction motors. This type of locomotive was first experimented with in 1920 but reached its peak in the 1950s to 1960s. The turbine (similar to a turboshaft engine) drives an output shaft, which drives the alternator via a system of gears. Aside from the unusual prime mover, a GTEL is very similar to a diesel-electric. In fact, the turbines built by GE used many of the same parts as their diesels. Referring to one of these as a gas turbine locomotive or even just a turbine locomotive will usually suffice, though there were exceptions. A few gas turbine locomotives used a mechanical transmission, and there were some steam turbine locomotives. ...more on Wikipedia about "Gas turbine-electric locomotive"
In 1925, the Deutsche Reichsbahn Gesellschaft (DRG, German Railway Company Limited) introduced a new system of steam locomotive classification. The DRG had inherited a wide range of locomotives from the state railways that had been merged in the previous year, and had a need to centrally catalog and organise its property. The scheme the DRG devised continued in use in a somewhat revised form until the German railways ceased to operate steam locomotives. ...more on Wikipedia about "German steam locomotive classification"
The double-ended HHP-8 electric locomotive is one of the latest editions from the Bombardier company which has re-entered the railroad equipment business. The engine is capable of 8000 hp and is expected to eventually completely replace the aging AEM7 engines in service for Amtrak's Northeast Corridor, though some " toasters" have been upgraded to match the hauling power of the HHP. The engine can haul considerably lengthy runs of Amfleet cars at about 135 mph. MARC ( Maryland) also operates HHP-8s on its Penn Line between Baltimore and Washington, DC. ...more on Wikipedia about "HHP-8"
A high pressure steam locomotive is a steam locomotive with a boiler that operates at pressures well above what would be considered normal. Typical steam locomotives had boiler pressures of 200 to 250 PSI, but some high pressure steam locomotives had boilers that operated at over 1,000 PSI. ...more on Wikipedia about "High pressure steam locomotive"
A hood unit, in railroad terminology, is a body style for locomotives. On a hood unit, the body of the locomotive is less than full-width for most of the locomotive's length, with walkways on the outside of the locomotive. In contrast, a cab unit has a full-width body for the length of the locomotive. A hood unit has sufficient visibility to be driven in both directions from a single driving cab. The hood unit's frame is the main load-bearing member, allowing the hoods containing locomotive equipment to be easily opened or even removed for maintenance access. These visibility and access advantages mean that the hood unit is overwhelmingly the most popular style of locomotive in North America and many other nations. ...more on Wikipedia about "Hood unit"
An inspection locomotive was a special type of steam locomotive designed to carry railroad officials on inspection tours of the railroad property. They were fitted with passenger car-like bodywork and seating. Many railroads in the 19th Century owned one, but their use dwindled in the 20th Century. They were replaced with converted passenger-car inspection cars, or inspection motor cars, automobiles fitted with steel flanged wheels. ...more on Wikipedia about "Inspection locomotive"
The American Locomotive Company (ALCO) produced a wide range of diesel locomotives until it ceased manufacture in 1969. This list is broken out of the main article to prevent it from growing unwieldy. ...more on Wikipedia about "List of ALCO diesel locomotives"

Following is a list of diesel locomotives built by the Montreal Locomotive Works, a Canadian subsidiary of the American Locomotive Company from 1904- 1964. From 1964- 1975 the company was knows as MLW-Worthington and was owned by Bombardier from 1975 until its closure in 1985. ...more on Wikipedia about "List of MLW diesel locomotives"
A locomotive (from lat. loco motivus) is a railway vehicle that provides the motive power for a train, and has no payload capacity of its own; its sole purpose is to move the train along the tracks. In contrast, many trains feature self-propelled payload-carrying vehicles; these are not normally considered locomotives, and may be referred to as multiple units or railcars; the use of these self-propelled vehicles is increasingly common for passenger trains, but very rare for freight (see however CargoSprinter). Vehicles which provide the motive power to haul an unpowered train, but are not generally considered locomotives because they have payload space or are rarely detached from their trains, are known as power cars. ...more on Wikipedia about "Locomotive"
The Locomotives of New Zealand consist of 172 diesel-electic locomotives, 22 electric locomotives, 59 electric multiple units, 29 diesel multiple units, 3 railcars, and 103 shunting locomotives currently in operation. There are also a small number of steam and diesel-electric locomotives as well as railcars in working order owned by private companies or preservation societies. ...more on Wikipedia about "Locomotives of New Zealand"
The Great Western Railway had an uninterrupted life of over a century to develop its locomotive designs as it was barely affected by the Grouping of 1923. As a result its locomotive history is a long and interesting one. For an explanation of numbering and classification, see British Locomotive and Multiple Unit Numbering and Classification. ...more on Wikipedia about "Locomotives of the Great Western Railway"
The London and North Eastern Railway (LNER) produced several classes of locomotive, mostly to the designs of Nigel Gresley, characterised by a three cylinder layout with a parallel boiler and round-topped firebox. It produced the most iconic locomotive of its day, 4468 'Mallard', the holder of the world steam locomotive speed record. It also built the world famous 4472 'Flying Scotsman'. However, its locomotive inheritance was much greater than just the 'A4 Class', it also produced highly successful mixed-traffic and freight designs. ...more on Wikipedia about "Locomotives of the London and North Eastern Railway"
Classification of Highland Railway Locomotives is a little messy. A systematic class identification system was in use at one point but just when is not documented. The system has it's problems in that some classes with early codes appeared after classes with later codes, classes E and F are a case in point. ...more on Wikipedia about "Locomotives of the London, Midland and Scottish Railway"
The Southern Railway took a key role in expanding the 660 V DC third rail electrified network begun by the London & South Western Railway. As a result of this, and its smaller operating area, its steam locomotive stock was the smallest of the 'Big Four' companies. Yet its locomotives were unique and of great interest. For an explanation of numbering and classification, see British Locomotive and Multiple Unit Numbering and Classification. ...more on Wikipedia about "Locomotives of the Southern Railway"
