4-4-2T
Under the Whyte notation for the classification of steam locomotives by wheel arrangement, represents a configuration of a four-wheeled leading bogie, four powered and coupled driving wheels, and two trailing wheels supporting part of the weight of the boiler and firebox. This allows a larger firebox and boiler than the configuration. This wheel arrangement is commonly known as the Atlantic type, although it is also sometimes called a Milwaukee or 4-4-2 Milwaukee, after the Milwaukee Road, which employed it in high speed passenger service. Overview While the wheel arrangement and type name Atlantic would come to fame in the fast passenger service competition between railroads in the United States by mid-1895, the tank locomotive version of the Atlantic type first made its appearance in the United Kingdom in 1880, when William Adams designed the 1 Class T of the London, Tilbury and Southend Railway (LT&SR).

LT&SR 1 Class
The London, Tilbury and Southend Railway 1 class was a class of 4-4-2T suburban tank engines. Thirty-six were built between 1880–1892, by Sharp, Stewart and Company and Nasmyth, Wilson and Company. They were the first locomotives owned by the London, Tilbury and Southend Railway and were the first 4-4-2T locomotives to operate in Britain. Background Prior to 3 July 1880, all train services on the London, Tilbury and Southend Railway (LT&SR) had been run by the Great Eastern Railway (GER) under contract. An injunction prevented the GER from building locomotives for the LT&SR after this date. The railway therefore approached William Adams, a former locomotive superintendent of the GER, then working for the London and South Western Railway who supervised the new design which was officially ascribed to Thomas Whitelegg. Design The design was based on William Adams's 46 class 4-4-0T but with driving wheels and an extended coal bunker supported by a radial truck making them t ...

London, Tilbury And Southend Railway
The London, Tilbury and Southend Railway (LT&SR), was a British railway company, whose network connected Fenchurch Street station, in central London, with destinations in east London and Essex, including , , , Tilbury, Southend and . The company and its assets were sold to the Midland Railway in 1912. The network over which they operated is largely intact and is currently operated as part of the Essex Thameside franchise. History Prior to opening In the mid 18th century south Essex was a thinly populated area and Barking, Southend and Leigh-on-sea were little more than villages. In June 1840 the London and Blackwall Railway (L&BR) started operation from Blackwall to a station called Minories and after a year this was extended to Fenchurch Street which was located close to the Tower of London. A month later in July 1840, the Eastern Counties Railway (ECR) opened their new station at Spitalfields and commenced running services to Brentwood and by 1843 this line had been extende ...

William Adams (locomotive Engineer)
William Adams (15 October 1823 – 7 August 1904) was an English railway engineer. He was the Locomotive Superintendent of the North London Railway from 1858 to 1873; the Great Eastern Railway from 1873 until 1878 and the London and South Western Railway from then until his retirement in 1895. He is best known for his locomotives featuring the ''Adams bogie'', a device with lateral centring springs (initially made of rubber) to improve high-speed stability. He should not be mistaken for William Bridges Adams (1797–1872) a locomotive engineer who, confusingly, invented the '' Adams axle'' – a radial axle that William Adams incorporated in designs for the London and South Western Railway. History Adams was born on 15 October 1823 in Mill Place, Limehouse, London, where his father was resident engineer of the nearby East and West India Docks Company. After private schooling in Margate, Kent he was apprenticed to his father's works. The railway surveyor Charles Vignoles had ...

Baldwin Locomotive Works
The Baldwin Locomotive Works (BLW) was an American manufacturer of railroad locomotives from 1825 to 1951. Originally located in Philadelphia, it moved to nearby Eddystone, Pennsylvania, in the early 20th century. The company was for decades the world's largest producer of steam locomotives, but struggled to compete as demand switched to diesel locomotives. Baldwin produced the last of its 70,000-plus locomotives in 1951, before merging with the Lima-Hamilton Corporation on September 11, 1951, to form the Baldwin-Lima-Hamilton Corporation. The company has no relation to the E.M. Baldwin and Sons of New South Wales, Australia, a builder of small diesel locomotives for sugar cane railroads. History: 19th century Beginning The Baldwin Locomotive Works had a humble beginning. Matthias W. Baldwin, the founder, was a jeweler and whitesmith, who, in 1825, formed a partnership with machinist David H. Mason, and engaged in the manufacture of bookbinders' tools and cylinders fo ...

Trailing Wheels
On a steam locomotive, a trailing wheel or trailing axle is generally an unpowered wheel or axle ( wheelset) located behind the driving wheels. The axle of the trailing wheels is usually located in a trailing truck. On some large locomotives, a booster engine was mounted on the trailing truck to provide extra tractive effort when starting a heavy train and at low speeds on gradients. Trailing wheels were used in some early locomotives but fell out of favor for a time during the latter 19th century. As demand for more powerful locomotives increased, trailing wheels began to be used to support the crew cab and rear firebox area. Trailing wheels first appeared on American locomotives between 1890 and 1895, but their axle worked in rigid pedestals. It enabled boilers to be lowered, since the top of the main frames was dropped down behind the driving wheels and under the firebox. The firebox could also be longer and wider, increasing the heating surface area and steam generation c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Firebox (steam Engine)
In a steam engine, the firebox is the area where the fuel is burned, producing heat to boil the water in the boiler. Most are somewhat box-shaped, hence the name. The hot gases generated in the firebox are pulled through a rack of tubes running through the boiler. Steam locomotive fire tube firebox In the standard steam locomotive fire-tube boiler, the firebox is surrounded by water space on five sides. The bottom of the firebox is open to atmospheric pressure, but covered by fire grates (solid fuel) or a firing pan (liquid fuel). If the engine burns solid fuel, like wood or coal, there is a grate covering most of the bottom of the firebox to hold the fire. An ashpan, mounted underneath the firebox and below the grates, catches and collects hot embers, ashes, and other solid combustion waste as it falls through the grates. In a coal-burning locomotive, the grates may be shaken to clean dead ash from the bottom of the fire. They are shaken either manually or (in larger locom ...

Driving Wheels
On a steam locomotive, a driving wheel is a powered wheel which is driven by the locomotive's pistons (or turbine, in the case of a steam turbine locomotive). On a conventional, non-articulated locomotive, the driving wheels are all coupled together with side rods (also known as coupling rods); normally one pair is directly driven by the main rod (or connecting rod) which is connected to the end of the piston rod; power is transmitted to the others through the side rods. On diesel and electric locomotives, the driving wheels may be directly driven by the traction motors. Coupling rods are not usually used, and it is quite common for each axle to have its own motor. Jackshaft drive and coupling rods were used in the past (e.g. in the Swiss Crocodile locomotive) but their use is now confined to shunting locomotives. On an articulated locomotive or a duplex locomotive, driving wheels are grouped into sets which are linked together within the set. Diameter Driving wheels ar ...

Atlantic Coast Line 4-4-2
Atlantic Coast Line 4-4-2 were express passenger tender locomotives built by Baldwin Locomotive Works (at that time known as Burnham, Williams & Co), initially for the Atlantic Coast Line Railroad The Atlantic Coast Line Railroad was a United States Class I railroad formed in 1900, though predecessor railroads had used the ACL brand since 1871. In 1967 it merged with long-time rival Seaboard Air Line Railroad to form the Seaboard Coas ... as classes I/I-2 and I-3. They were the first design in the world to exploit the larger boiler and firebox possible with a design compared to the classic . Design and build The advantages of the design included a large boiler and a firebox of "desirable form" with "ample depth and width" which could be fitted over the rear frames, and this design for the first to exploit those features. There were also claimed of improved riding compared to some other types. The design specification called for the ability to haul a ten-coach train up ...

Milwaukee Road Class A2
The Milwaukee Road's A2 class comprised 47 compound steam locomotives of the 4-4-2 or 'Atlantic' configuration. The Milwaukee Road acquired them in five batches. The first two batches of 9 and 19 locomotives (classes A2 and A2-a) were built by Baldwin Locomotive Works, and were Vauclain compound locomotives with drivers. The third batch (A2-b) of five locomotive was built by the Milwaukee Road in its Milwaukee, Wisconsin shops with drivers. The fourth batch (A2-c) of 12 engines was built by Baldwin as Vauclain compounds with drivers, while the last batch (A2) was for a pair of engines built by Baldwin as balanced compounds. All members of the class were scrapped between 1927–30.

Atlantic Coast Line Railroad
The Atlantic Coast Line Railroad was a United States Class I railroad formed in 1900, though predecessor railroads had used the ACL brand since 1871. In 1967 it merged with long-time rival Seaboard Air Line Railroad to form the Seaboard Coast Line Railroad. Much of the original ACL network has been part of CSX Transportation since 1986. The Atlantic Coast Line served the Southeast, with a concentration of lines in Florida. Numerous named passenger trains were operated by the railroad for Florida-bound tourists, with the Atlantic Coast Line contributing significantly to Florida's economic development in the first half of the 20th century. At the end of 1925, ACL operated 4,924 miles of road, not including its flock of subsidiaries; after some merging, mileage at the end of 1960 was 5,570 not including A&WP, CN&L, East Carolina, Georgia, Rockingham, and V&CS. In 1960, ACL reported 10,623 million net ton-miles of revenue freight and 490 million passenger-miles. History Early his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tender (rail)
A tender or coal-car (US only) is a special rail vehicle hauled by a steam locomotive containing its fuel (wood, coal, oil or torrefied biomass) and water. Steam locomotives consume large quantities of water compared to the quantity of fuel, so their tenders are necessary to keep them running over long distances. A locomotive that pulls a tender is called a tender locomotive. Locomotives that do not have tenders and carry all their fuel and water on board the locomotive itself are called tank locomotives. A corridor tender is a locomotive tender with a passageway to one side, allowing crew changes on the fly. A brake tender is a tender that is heavy and used (primarily) to provide greater braking efficiency. General functions The largest steam locomotives are semi-permanently coupled by a drawbar to a tender that carries the water and fuel. The fuel source used depends on what is economically available locally. In the UK and parts of Europe, a plentiful supply of coal made ...
