Baldwin RF-16
The BLH RF-16 is a cab unit-type diesel locomotive built for freight service by the Baldwin-Lima-Hamilton Corporation between 1950 and 1953. All RF-16s were configured with a B-B wheel arrangement and ran on two AAR Type B two-axle road trucks, with all axles powered. A total of 109 cab-equipped A units were built, along with 51 cabless booster B units, for a total of 160 locomotives built. As was the case with most passenger locomotives of its day, the RF-16s came equipped with a retractable, nose-mounted drop coupler pilot. Unlike competing units from EMD and Alco, the RF-16 used an air-powered throttle, meaning that it could not be run in MU operation with EMD or Alco diesels without special MU equipment. History In 1948, Baldwin began to apply a new "Sharknose" body style to its cab unit diesel locomotives. The goal of the new style was partly to differentiate Baldwin locomotives from competitors, and partly to distance the new locomotives from early Baldwin diesels ...

Escanaba And Lake Superior Railroad
The Escanaba & Lake Superior Railroad is a Class III shortline railroad that operates of track in Northeastern Wisconsin and the Upper Peninsula of Michigan. Its main line runs from Rockland, Michigan, to Green Bay, Wisconsin, and it also owns various branch lines and out-of-service track. In 1897, the Escanaba River Company built a railroad from Wells, Michigan to tap a large hardwood timber stand at LaFave’s Hill. In 1898, the company name was changed to the Escanaba & Lake Superior Railway (E&LS). History Founding to 1978 Isaac Stephenson, Jefferson Sinclair, Daniel Wells Jr., Harrison Ludington, and Nelson Ludington were the founders of the N. Ludington Company. It was again renamed to the I. Stephenson company when Isaac Stephenson became majority owner in the same year. The N. Ludington Company became part of this company, and along with being rebranded as the ''Escanaba River Company'', became a subsidiary of this new company in 1888. The Escanaba River Co. construc ...

Baldwin-Lima-Hamilton Corporation
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 for cali ...

AAR Wheel Arrangement
The AAR wheel arrangement system is a method of classifying locomotive (or unit) wheel arrangements that was developed by the Association of American Railroads. Essentially a simplification of the European UIC classification, it is widely used in North America to describe Diesel locomotive, diesel and electric locomotives (including third-rail electric locomotives). It is not used for steam locomotives, which use the Whyte notation instead. The AAR system counts axles instead of wheels. Letters refer to powered axles, and numbers to unpowered (or idler) axles. "A" refers to one powered axle, "B" to two powered axles in a row, "C" to three powered axles in a row, and "D" to four powered axles in a row. "1" refers to one idler axle, and "2" to two idler axles in a row. A dash ("–") separates Bogie, trucks or wheel assemblies. A plus sign ("+") refers to articulation, either by connecting bogies with span bolsters or by connecting individual locomotives via solid drawbars instead of ...

Prime Mover (locomotive)
In engineering, a prime mover is an engine that converts fuel to useful work. In locomotives, the prime mover is thus the source of power for its propulsion. In an engine-generator set, the engine is the prime mover, as distinct from the generator. Definition In a diesel-mechanical locomotive, the prime mover is the diesel engine that is mechanically coupled to the driving wheels (drivers). In a diesel-electric locomotive, the prime mover is the diesel engine that rotates the main generator responsible for producing electricity to power the traction motors that are geared to the drivers. The prime mover can also be a gas turbine instead of a diesel engine. In either case, the generator, traction motors and interconnecting apparatus are considered to be the power transmission system and not part of the prime mover. A wired-electric or battery-electric locomotive has no on-board prime mover, instead relying on an external power station. Weight distribution The power unit rep ...

Locomotive
A locomotive or engine is a rail transport vehicle that provides the Power (physics), motive power for a train. If a locomotive is capable of carrying a payload, it is usually rather referred to as a multiple unit, Motor coach (rail), motor coach, railcar or power car; the use of these self-propelled vehicles is increasingly common for passenger trains, but rare for freight (see CargoSprinter). Traditionally, locomotives pulled trains from the front. However, Push-pull train, push-pull operation has become common, where the train may have a locomotive (or locomotives) at the front, at the rear, or at each end. Most recently railroads have begun adopting DPU or distributed power. The front may have one or two locomotives followed by a mid-train locomotive that is controlled remotely from the lead unit. __TOC__ Etymology The word ''locomotive'' originates from the Latin language, Latin 'from a place', Ablative case, ablative of 'place', and the Medieval Latin 'causing mot ...

Duplex Locomotive
A duplex locomotive is a steam locomotive that divides the driving force on its wheels by using two pairs of cylinders rigidly mounted to a single locomotive frame; it is not an articulated locomotive. The concept was first used in France in 1863, but was particularly developed in the early 1930s by the Baldwin Locomotive Works, the largest commercial builder of steam locomotives in North America, under the supervision of its then chief engineer, Ralph P. Johnson. Prior to this, the term ''duplex locomotive'' was sometimes applied to articulated locomotives in general. Drawbacks of the two-cylinder locomotive The duplex solution In Europe this problem was often overcome by dividing the drive between inside and outside cylinders, or else by using Articulated locomotives, although at the time it was not believed possible to run one stably at greater than . American railroads proved to be unwilling to use locomotives with inside cylinders, so the problem of balance could not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PRR T1
The Pennsylvania Railroad (PRR) class T1 duplex-drive 4-4-4-4 steam locomotives, introduced in 1942 with two prototypes and later in 1945-1946 with 50 production examples, were the last steam locomotives built for the PRR and arguably its most controversial. They were ambitious, technologically sophisticated, powerful, fast and distinctively streamlined by Raymond Loewy. However, they were also prone to wheelslip both when starting and at speed, in addition to being complicated to maintain and expensive to run. The PRR decided in 1948 to place diesel locomotives on all express passenger trains, leaving unanswered questions as to whether the T1's flaws were solvable, especially taking into account that the two prototypes did not have the problems inherent to the production units. An article appearing in a 2008 issue of the Pennsylvania Railroad Technical and Historical Society Magazine showed that inadequate training for engineers transitioning to the T1 may have led to exces ...
