Renfe Class 309
The Renfe Class 309 is a class of 20 three axle diesel-hydraulic locomotives shunters built by M.T.M. for Renfe, and introduced between 1986-7. History and design In the late 1970s Renfe began planning to modernise its shunting locomotives; initially modernisation of the Class 303 with new engines was considered and one locomotive converted, but the experiment was not carried forward. In 1982 Renfe opened bidding for a contract for 50 locomotives of up to . M.T.M. ('' Maquinista Terrestre y Marítima'') offered its own development, and was successful: in July 1983 Renfe placed an order for 20 units. The first units were delivered in the red-brown/yellow/white ''estrella'' livery in 1985 and were accepted into service in 1986 after correction of technical problems. Initially the property of Renfe, after the creation of Adif the locomotives were divided between ''Mercancías'' (formerly ''Cargas'' freight) and Adif (infrastructure services). As of 2010 about half have been ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel-hydraulic
A diesel locomotive is a type of railway locomotive in which the prime mover (locomotive), prime mover 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. Early internal combustion engine, internal combustion locomotives and railcars used kerosene and gasoline as their fuel. Rudolf Diesel patented his first compression-ignition engine in 1898, and steady improvements to the design of diesel engines reduced their physical size and improved their power-to-weight ratios to a point where one could be mounted in a locomotive. Internal combustion engines only operate efficiently within a limited power band, and while low power gasoline engines could be coupled to mechanical transmission (mechanics), transmissions, the more powerful diesel engines required the development of new forms of transmission. This is because clutches would need to be very large at these power le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

5 Ft 6 In Gauge Locomotives
5 (five) is a number, numeral (linguistics), numeral and numerical digit, digit. It is the natural number, and cardinal number, following 4 and preceding 6, and is a prime number. It has attained significance throughout history in part because typical humans have five Digit (anatomy), digits on each hand. In mathematics 5 is the third smallest prime number, and the second super-prime. It is the first safe prime, the first good prime, the first balanced prime, and the first of three known Wilson primes. Five is the second Fermat prime and the third Mersenne prime exponent, as well as the third Catalan number, and the third Sophie Germain prime. Notably, 5 is equal to the sum of the ''only'' consecutive primes, 2 + 3, and is the only number that is part of more than one pair of twin primes, (3, 5) and (5, 7). It is also a sexy prime with the fifth prime number and first Repunit#Decimal repunit primes, prime repunit, 11 (number), 11. Five is the third factorial prime, an alternat ...

309 Diesel
3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious or cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. The Indian digits spread to the Caliphate in the 9th ce ...

Shunter
A switcher, shunter, yard pilot, switch engine, yard goat, or shifter is a small railroad locomotive used for manoeuvring railroad cars inside a rail yard in a process known as ''switching'' (US) or ''shunting'' (UK). Switchers are not intended for moving trains over long distances but rather for assembling trains in order for another locomotive to take over. They do this in classification yards (Great Britain: ''marshalling yards''). Switchers may also make short transfer runs and even be the only motive power on branch lines and switching and terminal railroads. The term can also be used to describe the workers operating these engines or engaged in directing shunting operations. Switching locomotives may be purpose-built engines, but may also be downgraded main-line engines, or simply main-line engines assigned to switching. Switchers can also be used on short excursion train rides. The typical switcher is optimised for its job, being relatively low-powered but with a high ...
