Barry Railway Class L
Barry Railway Class L were 0-6-4T steam tank locomotives of the Barry Railway in South Wales. They were designed by John Auld (locomotive designer), John Auld, his only design for the Barry Railway, built by Hawthorn Leslie and Company and were introduced in 1914. They were originally intended for use on heavy coal trains from Trehafod but, as the B1 class proved more than adequate for the work, they were assigned to different duties. These included pulling mineral trains from Rhymney and New Tredegar on the Brecon and Merthyr, from Rogerstone Yard on the Great Western and from Neath Junction, also on the Great Western. They were also to be seen occasionally pulling the suburban service to Cardiff. Design fault One characteristic of the locomotive was a design fault that caused it to derail. The problem would only occur when the locomotive was travelling smokebox-first over facing hand-operated Railroad switch, points, usually to be found in colliery sidings, marshalling yards ...

Ticker Symbol
A ticker symbol or stock symbol is an abbreviation used to uniquely identify publicly traded shares of a particular stock on a particular stock market. In short, ticker symbols are arrangements of symbols or characters (generally Latin letters or digits) representing specific assets or securities listed on a stock exchange or traded publicly. A stock symbol may consist of letters, numbers, or a combination of both. "Ticker symbol" refers to the symbols that were printed on the ticker tape of a ticker tape machine. Interpreting the symbol Stock symbols are unique identifiers assigned to each security traded on a particular market. A stock symbol can consist of letters, numbers, or a combination of both, and is a way to uniquely identify that stock. The symbols were kept as short as possible to reduce the number of characters that had to be printed on the ticker tape, and to make it easy to recognize by traders and investors. The allocation of symbols and formatting conventions ...

L (complexity)
In computational complexity theory, L (also known as LSPACE or DLOGSPACE) is the complexity class containing decision problems that can be solved by a deterministic Turing machine using a logarithmic amount of writable memory space., Definition 8.12, p. 295., p. 177. Formally, the Turing machine has two tapes, one of which encodes the input and can only be read, whereas the other tape has logarithmic size but can be read as well as written. Logarithmic space is sufficient to hold a constant number of pointers into the input and a logarithmic number of boolean flags, and many basic logspace algorithms use the memory in this way. Complete problems and logical characterization Every non-trivial problem in L is complete under log-space reductions, so weaker reductions are required to identify meaningful notions of L-completeness, the most common being first-order reductions. A 2004 result by Omer Reingold shows that USTCON, the problem of whether there exists a pat ...

L-class Star
Brown dwarfs (also called failed stars) are substellar objects that are not massive enough to sustain nuclear fusion of ordinary hydrogen ( 1H) into helium in their cores, unlike a main-sequence star. Instead, they have a mass between the most massive gas giant planets and the least massive stars, approximately 13 to 80 times that of Jupiter (). However, they can fuse deuterium ( 2H), and the most massive ones (> ) can fuse lithium ( 7Li). Astronomers classify self-luminous objects by spectral class, a distinction intimately tied to the surface temperature, and brown dwarfs occupy types M, L, T, and Y. As brown dwarfs do not undergo stable hydrogen fusion, they cool down over time, progressively passing through later spectral types as they age. Despite their name, to the naked eye, brown dwarfs would appear in different colors depending on their temperature. The warmest ones are possibly orange or red, while cooler brown dwarfs would likely appear magenta or black to the ...

L-class Blimp
The L-class blimps were training airships operated by the United States Navy during World War II. In the mid-1930s, the Goodyear Aircraft Company built a family of small non-rigid airships that the company used for advertising the Goodyear name. In 1937 the United States Navy awarded a contract for two different airships, K-class blimp designated K-2 and a smaller blimp based upon Goodyear's smaller commercial model airship used for advertising and passenger carrying. The smaller blimp was designated by the Navy as L-1. It was delivered in April 1938 and operated from the Navy's lighter-than-air facility at Lakehurst, New Jersey. In the meantime, the Navy ordered two more L-Class blimps, the L-2 and L-3, on September 25, 1940. These were delivered in 1941. L-2 was lost in a nighttime mid-air collision with the G-1 on June 8, 1942. When the United States entered World War II, the Navy took over the operation of Goodyear's five commercial blimps. These were the ''Resolute'', '' ...

L-class Sydney Tram
The F-class trams were a class of two-bogie California combination car trams operated on the Sydney tram network with longitudinal seating in the open part of the car. They were later rebuilt as the L-class trams and some again as the L/P-class trams. History In 1899, F122 was built by Clyde Engineering as a prototype. Deemed a success, a further 250 were built by Clyde Engineering between 1900 and 1902. They were introduced for the electrification of the Eastern Suburbs, South-Western and Western lines. Between 1906 and 1914, all were converted to L class trams at Randwick Tramway Workshops with the open seating altered to a cross-bench configuration, like the K and O class trams, rather than the original cable-tram style outward-facing longitudinal seating. F393 was not included, having been converted to a driver training car. Between 1918 and 1930, all L class were rebuilt to resemble the P class trams as the L/P class. In 1920, 16 were allocated to the Rockdale Line while ...

Highland Railway L Class
The Highland Railway L class, also known as ‘Skye Bogies’ due to their association with the Kyle of Lochalsh Line. They were essentially mixed traffic versions of the earlier ''Duke'' or F class. Construction Nine were built at Lochgorm Works over the period 1882 to 1901. They were never named. Dimensions The cylinders, valve gear and motion were common to the two classes, but they had smaller driving wheels and higher pressure boilers.
