British Rail Class 125
The British Rail Class 125 was a design of three car Diesel Multiple Unit built by BR Derby at Derby Works in 1958. They were almost identical in appearance to the Class 116. History The Class 125 was built in 1958 at Derby Works as high capacity suburban railcars specifically for the Lea Valley Lines near Stratford. They were fitted with powerful Rolls-Royce engines, allowing them to have comparable performance to contemporary EMUs.They bore a close resemblance to the similar class 116, which were also built by British Rail at Derby. The Class 125 had a unique multiple working code (orange star), due to their unique pneumatic, rather than electric, engine control system. They also had a non-standard jumper cable arrangement and were therefore incompatible with other British Rail diesel multiple unit classes. They were withdrawn in 1977 and like many other first generation DMUs, never wore their Class 125 TOPS classifications. Operational history The class 125 entered ...

Broad Street Railway Station (London)
Broad Street was a major terminal station in the City of London, adjacent to Liverpool Street station. It served as the main terminus of the North London Railway (NLR) network, running from 1865 to 1986. During its lifetime, it catered for mainly local suburban services around London, and over time struggled to compete with other modes of transport, leading to its closure. The station was built as a joint venture by the NLR and the London and North Western Railway (LNWR) in order to have a station serving freight closer to the City. It was immediately successful for both goods and passenger services and saw a significant increase in NLR traffic. Usage peaked in the early 20th century, after which it suffered from competition of London trams,_buses,_and_particularly_the_London_Underground.html" ;"title=""type": ..., buses, and particularly the London Underground">"type": ..., buses, and particularly the London Underground network.

Diesel Multiple Unit
A diesel multiple unit or DMU is a multiple-unit train powered by on-board diesel engines. A DMU requires no separate locomotive, as the engines are incorporated into one or more of the carriages. Diesel-powered single-unit railcars are also generally classed as DMUs. Diesel-powered units may be further classified by their transmission type: diesel–mechanical DMMU, diesel–hydraulic DHMU, or diesel–electric DEMU. Design The diesel engine may be located above the frame in an engine bay or under the floor. Driving controls can be at both ends, on one end, or in a separate car. Types by transmission DMUs are usually classified by the method of transmitting motive power to their wheels. Diesel–mechanical In a diesel–mechanical multiple unit (DMMU), the rotating energy of the engine is transmitted via a gearbox and driveshaft directly to the wheels of the train, like a car. The transmissions can be shifted manually by the driver, as in the great majority of first-gene ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buffer Beam
A headstock of a rail vehicle is a transverse structural member located at the extreme end of the vehicle's underframe. The headstock supports the coupling at that end of the vehicle, and may also support buffers, in which case it may also be known as a buffer beam. The headstocks form part of the underframe of a locomotive or a railroad car. The headstocks of locomotives, railcars and cabcars also support headlamps and the hoses for air brakes, vacuum brakes as well as the cables for train control and head end power. Length over headstocks A commonly used measurement relating to a rail vehicle is its length over headstocks, which is the length of the vehicle excluding its couplings or buffers (if any). Alternative expressions for length over headstocks are length over coupler pulling faces, usually applied to Janney couplers, and length over buffers.

Derby
Derby ( ) is a city and unitary authority area in Derbyshire, England. It lies on the banks of the River Derwent in the south of Derbyshire, which is in the East Midlands Region. It was traditionally the county town of Derbyshire. Derby gained city status in 1977, the population size has increased by 5.1%, from around 248,800 in 2011 to 261,400 in 2021. Derby was settled by Romans, who established the town of Derventio, later captured by the Anglo-Saxons, and later still by the Vikings, who made their town of one of the Five Boroughs of the Danelaw. Initially a market town, Derby grew rapidly in the industrial era. Home to Lombe's Mill, an early British factory, Derby has a claim to be one of the birthplaces of the Industrial Revolution. It contains the southern part of the Derwent Valley Mills World Heritage Site. With the arrival of the railways in the 19th century, Derby became a centre of the British rail industry. Derby is a centre for advanced transport manu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Technical Centre
The Railway Technical Centre (RTC) in London Road, Derby, England, was the technical headquarters of the British Railways Board, and was built in the early 1960s. British Rail described it as the largest railway research complex in the world. The RTC centralised most of the technical services provided by the regional Chief Mechanical & Electrical Engineers (CM&EE) to form the Department of Mechanical & Electrical Engineering (DM&EE). In addition, it housed the newly formed British Rail Research Division which reported directly to the Board. The latter is well known for its work on the experimental Advanced Passenger Train (APT-E). At that early stage this was a concept vehicle, and in time the DM&EE applied the new knowledge to existing practice in the design of the High Speed Train (HST), the later prototype APT-P and other high-speed vehicles. History Opening The Research Division was the first to move into the purpose-built accommodation on London Road. This was formed initial ...

London King's Cross Railway Station
King's Cross railway station, also known as London King's Cross, is a passenger railway terminus in the London Borough of Camden, on the edge of Central London. It is in the London station group, one of the busiest stations in the United Kingdom and the southern terminus of the East Coast Main Line to North East England and Scotland. Adjacent to King's Cross station is St Pancras International, the London terminus for Eurostar services to continental Europe. Beneath both main line stations is King's Cross St Pancras tube station on the London Underground; combined they form one of the country's largest and busiest transport hubs. The station was opened in Kings Cross in 1852 by the Great Northern Railway on the northern edge of Central London to accommodate the East Coast Main Line. It quickly grew to cater for suburban lines and was expanded several times in the 19th century. It came under the ownership of the London and North Eastern Railway as part of the Big Four g ...

British Rail Class 308
The British Rail Class 308 alternating current (AC) electric multiple units (EMU) were built by British Railways' Holgate Road carriage works in three batches between 1959 and 1961. They were initially classified as AM8 units before the introduction of TOPS. Description Class 308/1 The first batch of 33 units were built in 1959, classified as AM8 and numbered 133–165. This was later changed to Class 308/1 under the TOPS system, and units were renumbered 308133–165. These units were built to operate commuter services on the Great Eastern Main Line (GEML) from to , , , and . Each unit was formed of four carriages: two outer driving trailers, an intermediate trailer, and a motor coach. Electrically the Class 308 stock has the same equipment as the Class 302 stock with a few modifications, some of these are the types of overload, the use of fan-cooled rectifier continued until the rectifiers were modified to 8-diode type from 1982. This modified main rectifier was also m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Rail Class 302
The British Rail Class 302 (pre- TOPS AM2) was a type of electric multiple unit (EMU) introduced between 1958 and 1960 for outer suburban passenger services on the London, Tilbury and Southend line. This class of multiple unit was constructed using the Mark 1 bodyshell and was slam-door. Overview Like all the Eastern Region AC EMUs of the period, they were equipped to operate on both 25 kV AC and the reduced 6.25 kV voltage in the inner London areas where headroom for the overhead wires was reduced. On the LT&S the changeover point was just east of Barking station on both Upminster and Tilbury routes with the link to Forest Gate being at 6.25kV ac. Each unit was formed of four coaches, in the following formation: DTSOL (Driving Trailer Second Open with Lavatory) – MBS (Motor Brake Second) – TCsoL (Trailer Composite semi-open with Lavatory) – DTS (Driving Trailer Second). The initial set numbers were 201–312, later prefixed by the class number 302 with the introductio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrification
Electrification is the process of powering by electricity and, in many contexts, the introduction of such power by changing over from an earlier power source. The broad meaning of the term, such as in the history of technology, economic history, and economic development, usually applies to a region or national economy. Broadly speaking, electrification was the build-out of the electricity generation and electric power distribution systems that occurred in Britain, the United States, and other now- developed countries from the mid-1880s until around 1950 and is still in progress in rural areas in some developing countries. This included the transition in manufacturing from line shaft and belt drive using steam engines and water power to electric motors. The electrification of particular sectors of the economy is called by terms such as ''factory electrification'', ''household electrification'', ''rural electrification'', ''aviation electrification'' or '' railway electrif ...

TOPS
Total Operations Processing System (TOPS) is a computer system for managing railway locomotives and rolling stock, known for many years of use in the United Kingdom. TOPS was originally developed between the Southern Pacific Railroad (SP), Stanford University and IBM as a replacement for paper-based systems for managing rail logistics. A jointly-owned consultancy company, ''TOPS On-Line Inc.'', was established in 1960 with the goal of implementing TOPS, as well as selling it to third parties. Development was protracted, requiring around 660 man-years of effort to produce a releasable build. During mid-1968, the first phase of the system was introduced on the SP, and quickly proved its advantages over the traditional methods practiced prior to its availability. In addition to SP, TOPS was widely adopted throughout North America and beyond. While it was at one point in widespread use across many of the United States railroads, the system has been perhaps most prominently used ...

Electric Multiple Unit
An electric multiple unit or EMU is a multiple-unit train consisting of self-propelled carriages using electricity as the motive power. An EMU requires no separate locomotive, as electric traction motors are incorporated within one or a number of the carriages. An EMU is usually formed of two or more semi-permanently coupled carriages, but electrically powered single-unit railcars are also generally classed as EMUs. The great majority of EMUs are passenger trains, but versions also exist for carrying mail. EMUs are popular on commuter and suburban rail networks around the world due to their fast acceleration and pollution-free operation. Being quieter than diesel multiple units (DMUs) and locomotive-hauled trains, EMUs can operate later at night and more frequently without disturbing nearby residents. In addition, tunnel design for EMU trains is simpler as no provision is needed for exhausting fumes, although retrofitting existing limited-clearance tunnels to accommodate the ex ...
