Slug (railroad)
In railroading, a slug is a version of a diesel–electric locomotive which lacks a Prime mover (locomotive), prime mover and often a cab. It derives the electrical power needed to operate its traction motors and motor controls from a fully-powered mother locomotive. At low speeds the drawing (or regenerative braking, braking) force a diesel–electric locomotive can produce is often limited by its traction motors or the grip of its drive wheels on the track, not the capability of its diesel engine(s). A slug adds more traction motors and drive wheels to both use more of the power the mother's engine can produce that cannot otherwise be used at low speeds and provide better braking, without the expense of a full locomotive. A slug is distinct from a B unit, which has both a prime mover and traction motors but no cab. A slug may have an operator's cab to allow engineers to operate a train with the slug in the lead, or the cab and much of the body can be omitted to reduce cost an ...

Train
A train (from Old French , from Latin">-4; we might wonder whether there's a point at which it's appropriate to talk of the beginnings of French, that is, when it wa ... , from Latin , "to pull, to draw") is a series of connected vehicles that run along a railway track and Passenger train, transport people or Rail freight transport, freight. Trains are typically pulled or pushed by locomotives (often known simply as "engines"), though some are self-propelled, such as multiple units or railcars. Passengers and cargo are carried in railroad cars, also known as wagons or carriages. Trains are designed to a certain gauge, or distance between rails. Most trains operate on steel tracks with steel wheels, the low friction of which makes them more efficient than other forms of transport. Many countries use rail transport. Trains have their roots in wagonways, which used railway tracks and were powered by horses or pulled by cables. Following the invention of the steam locomo ...

Seaboard Coast Line Railroad
The Seaboard Coast Line Railroad was a Class I railroad company operating in the Southeastern United States beginning in 1967. Its passenger operations were taken over by Amtrak in 1971. Eventually, the railroad was merged with its affiliate lines to create the Seaboard System in 1983. At the end of 1970, SCL operated 9,230 miles of railroad, not including A&WP-Clinchfield-CN&L-GM-Georgia-L&N-Carrollton; that year it reported 31,293 million ton-miles of revenue freight and 512 million passenger-miles. History The Seaboard Coast Line emerged on July 1, 1967, following the merger of the Seaboard Air Line Railroad with the Atlantic Coast Line Railroad. The combined system totaled , the eighth largest in the United States at the time. The railroad had $1.2 billion in assets and revenue with a 54% market share of rail service in the Southeast, facing competition primarily from the Southern. The seemingly redundant name resulted from the longstanding short-form names of these two ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GE U25B
The GE U25B is General Electric's first independent entry into the United States domestic road switcher diesel-electric locomotive railroad market for heavy production road locomotives since 1936. From 1940 through 1953, GE participated in a design, production, and marketing consortium ( Alco-GE) for diesel-electric locomotives with the American Locomotive Company. In 1956 the GE Universal Series of diesel locomotives was founded for the export market. The U25B was the first attempt at the domestic market since its termination of the consortium agreement with Alco. History The U25B (nicknamed ''U-Boat'') is the first commercially successful domestic diesel electric road locomotive designed, built, and sold by General Electric after its split with the American Locomotive Company (Alco), a company dating back to the steam era.

Radiator
A radiator is a heat exchanger used to transfer thermal energy from one medium to another for the purpose of cooling and heating. The majority of radiators are constructed to function in cars, buildings, and electronics. A radiator is always a source of heat to its environment, although this may be for either the purpose of #Heating, heating an environment, or for cooling the fluid or coolant supplied to it, as for automotive #Engine cooling, engine cooling and Heating, ventilation, and air conditioning, HVAC dry cooling towers. Despite the name, most radiators transfer the bulk of their heat via convection instead of thermal radiation. History The Roman hypocaust is an early example of a type of radiator for building space heating. Franz San Galli, a Prussia, Prussian-born Russian businessman living in St. Petersburg, is credited with inventing the heating radiator around 1855, having received a radiator patent in 1857, but American Joseph Nason and Scot Rory Gregor developed a ...
