Roadrailer
RoadRailers were a trailer or semi-trailer that could be hauled on roads by a tractor unit and then by way of a fifth wheel coupling, operate in a unit train on railway lines. The RoadRailer system allowed trailers to be pulled by locomotives without the use of flatcars, instead attaching trailers directly to bogies. Overview The advantage of using roadrailers was their ability to be used directly behind other freight (or even passenger) equipment without the use of trailer flatcars. Roadrailers first appeared on American railroads in the 1950s. The trailers were built with integrated railroad wheelsets that could be lowered into position when the trailer was pulled behind a train. More modern roadrailers did not include integrated railroad wheels, but rode on regular trucks that do double-duty, having served as articulation points between multiple trailers in a train. Each regular truck is equipped with one fifth wheel at one end and a connector plate at the other en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trailer (vehicle)
A trailer is an unpowered vehicle Towing, towed by a powered vehicle. It is commonly used for the transport of goods and materials. There are two general categories of trailers: the full trailer and the semitrailer. A full trailer is a type of trailer whose entire weight is supported by its own wheels, with no weight transferred to the towing vehicle. In contrast, a semi-trailer is designed so that a portion of its weight is carried by its own wheels, while the remaining weight is borne by the towing vehicle. Sometimes recreational vehicles, travel trailers, or mobile homes with limited living facilities where people can camp or stay have been referred to as trailers. In earlier days, many such vehicles were towable trailers. Trailers have been used for thousands of years, predating the invention of the automobile. Before the advent of the wheel, early humans employed the concept of trailering by using drag sleds to transport goods. While the two wheel war chariot is one of the ...

End-of-train Device
The end of train device (ETD), sometimes referred to as an EOT, flashing rear-end device (FRED) or sense and braking unit (SBU) is an electronic device mounted on the end of freight trains in replacement of a caboose. They are divided into three categories: "dumb" units, which only provide a visible indication of the rear of the train with a flashing red taillight; "average intelligence" units with a brake pipe pressure gauge; and "smart" units, which send back data to the crew in the locomotive via radio-based telemetry. They originated in North America, and are also used elsewhere in the world, where they may include complete End of Train Air System (ETAS) or Sense and Brake Unit (SBU) devices. Tail lamps The earliest known method of showing the position of and completeness of a train was by the Stockton and Darlington Railway in the 1830s. These early references are to the use of a burning brazier on the rear of the locomotive. It is easy to imagine that the danger represe ...

Caboose
A caboose is a crewed North American railroad car coupled at the end of a freight train. Cabooses provide shelter for crew at the end of a train, who were formerly required in switching and shunting; as well as in keeping a lookout for load shifting, damage to equipment and cargo, and overheating axles. Originally flatcars fitted with cabins or modified box cars, they later became purpose-built, with bay windows above or to the sides of the car to allow crew to observe the train. The caboose also served as the conductor's office, and on long routes, included sleeping accommodations and cooking facilities. A similar railroad car, the brake van, was used on British and Commonwealth railways outside North America (the role has since been replaced by the crew car in Australia). On trains not fitted with continuous brakes, brake vans provided a supplementary braking system, and they helped keep chain couplings taut. Cabooses were used on every freight train in the United ...

Loading Gauge
A loading gauge is a diagram or physical structure that defines the maximum height and width dimensions in railway vehicles and their loads. Their purpose is to ensure that rail vehicles can pass safely through tunnels and under bridges, and keep clear of platforms, trackside buildings and structures. Classification systems vary between different countries, and loading gauges may vary across a network, even if the track gauge is uniform. The term loading gauge can also be applied to the maximum size of road vehicles in relation to tunnels, overpasses and bridges, and doors into automobile repair shops, bus garages, filling stations, residential garages, multi-storey car parks and warehouses. A related but separate gauge is the structure gauge, which sets limits to the extent that bridges, tunnels and other infrastructure can encroach on rail vehicles. The difference between these two gauges is called the clearance. The specified amount of clearance makes allowance for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Squat Position
Squatting is a versatile posture where the weight of the body is on the feet but the knees and hips are bent. In contrast, sitting involves supporting the weight of the body on the ischial tuberosities of the pelvis, with the lower buttocks in contact with the ground or a horizontal object. The angle between the legs when squatting can vary from zero to widely splayed out, flexibility permitting. Another variable may be the degree of forward tilt of the upper body from the hips. Squatting may be either full or partial. Crouching is usually considered to be synonymous with squatting. It is common to squat with one leg and kneel with the other leg. One or both heels may be up when squatting. Young children often instinctively squat. Among Chinese, Southeast Asian and Eastern European adults, squatting often takes the place of sitting or standing. Etymology Squatting comes from the Old French ''esquatir/escatir'', meaning to "compress/press down".Harper, D. (n.d.). Etymology of sq ...

Chesapeake & Ohio Railway
The Chesapeake and Ohio Railway was a Class I railroad formed in 1869 in Virginia from several smaller Virginia railroads begun in the 19th century. Led by industrialist Collis Potter Huntington, it reached from Virginia's capital city of Richmond to the Ohio River by 1873, where the railroad town (and later city) of Huntington, West Virginia, was named for him. History 19th century The C&O traces its origins to the Louisa Railroad of Louisa County, Virginia, begun in 1836. By 1850, the Louisa was built east to Richmond and west to Charlottesville, and in keeping with its new and larger vision, was renamed the Virginia Central Railroad. The Commonwealth of Virginia owned a portion of Virginia Central stock and financed the Blue Ridge Railroad to accomplish the task of crossing the first mountain barrier to the west. During the American Civil War, the Virginia Central played a key role in several battles but was a target for Federal armies. By 1865, it only had five miles of ...
