Lidgerwood was a historic American engineering company famous for its boilers, winches, scrapers, hoists and cranes, [1] particularly ones that helped build the Panama Canal. [2] [3] They later built logging yarders and aerial tramways, cable cars or ropeways. [4]
Lidgerwood winches had at least two specific railroad maintenance uses, and were used by railroad customers to move railroad freight cars into position for loading and unloading (and to move other cars out of the way). As the successor company is still in business it is probable that they continue to be used in the railroad industry for moving cars through current (2013) times.
Railroad wheels need to have a specific profile. As the profile wears into degraded shapes their performance becomes irregular and eventually unsafe. Most wheels are re-profiled using some variation of a wheel lathe or milling machine; but it is impractical to position steam locomotives over a lathe or to remove the wheels for re-profiling (although shop lathes do re-profile dis-mounted drive wheels when the locomotive is already disassembled). Instead, a winch – known colloquially as "The Lidgerwood" on some railroads – would move the locomotive while cutting heads were mounted on brake shoe brackets and forced against the wheels. As the locomotive moved against the cutting heads, its wheels were cut back to a desirable profile. In a locomotive maintenance facility of the steam engine era (until, generally, the mid-1950s in the US) the place where this was done was sometimes known as the "Lidgerwood Track".
Maintenance of a railroad embankment may require material (soil, rock, etc.) to be moved from where it is deposited by erosion near the track to a place where the embankment has been eroded away, or a railroad may need to simply widen the cut and fill sections. One method to do this was to mount a winch on one flat car (colloquially known as the Lidgerwood Car and in some cases labeled as such) with a line connected to a plow that was configured to slide along the decks of many flat cars. Soil material was shoveled (manually or by power equipment) onto the flat cars then the train of flat cars was moved to where the material was to be unloaded and the plow was pulled over the decks, forcing the material laterally off the flat cars where it fell to the embankment. [5]
Arriving near the scene of the dump, another engine, having in front of it a huge horizontal steam windlass mounted on a flat car, was hooked on the rear end of the train. Then the locomotive which had brought the train to the dump was uncoupled and moved away, and in its stead there was attached an empty flat car, on which there was a huge plow. A long wire cable was stretched from the big windlass at the other end of the train and attached to this plow. As the drum of the windlass began to turn it gradually drew the plow forward over the 21 cars, plowing the material off as it went forward. The cars were equipped with a high sideboard on one side and had none at all on the other. A flat surface over which the plow could pass from car to car was made by hinging a heavy piece of sheet steel to the front end of each car and allowing it to cover the break between that car and the next, thus affording a practically continuous car floor over 800 feet long. The operation of unloading 400 yards of material with this plow seldom required more than 10 minutes.
A locomotive or engine is a rail transport vehicle that provides the 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, railcar or power car; the use of these self-propelled vehicles is increasingly common for passenger trains, but rare for freight.
In rail transport, a train is a series of connected vehicles that run along a railway track and transport people or freight. Trains are typically pulled or pushed by locomotives, though some are self-propelled, such as multiple units. Passengers and cargo are carried in railroad cars, also known as wagons. 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.
A railroad car, railcar, railway wagon, railway carriage, railway truck, railwagon, railcarriage or railtruck, also called a train car, train wagon, train carriage or train truck, is a vehicle used for the carrying of cargo or passengers on a rail transport system. Such cars, when coupled together and hauled by one or more locomotives, form a train. Alternatively, some passenger cars are self-propelled in which case they may be either single railcars or make up multiple units.
A winch is a mechanical device that is used to pull in or let out or otherwise adjust the tension of a rope or wire rope.
A crane is a type of machine, generally equipped with a hoist rope, wire ropes or chains, and sheaves, that can be used both to lift and lower materials and to move them horizontally. It is mainly used for lifting heavy objects and transporting them to other places. The device uses one or more simple machines to create mechanical advantage and thus move loads beyond the normal capability of a human. Cranes are commonly employed in transportation for the loading and unloading of freight, in construction for the movement of materials, and in manufacturing for the assembling of heavy equipment.
The Panama Canal Railway is a railway line linking the Atlantic Ocean to the Pacific Ocean in Central America. The route stretches 47.6 miles (76.6 km) across the Isthmus of Panama from Colón (Atlantic) to Balboa. Because of the difficult physical conditions of the route and state of technology, the construction was renowned as an international engineering achievement, one that cost US$8 million and the lives of an estimated 5,000 to 10,000 workers. Opened in 1855, the railway preceded the Panama Canal by half a century; the railway was vital in assisting the construction of the canal in the early 1900s. With the opening of the canal, the railroad's route was changed as a result of the creation of Gatun Lake, which flooded part of the original route. Following World War II, the railroad's importance declined and much of it fell into a state of neglect until 1998, when a project to rebuild the railroad to haul intermodal traffic began; the new railroad opened in 2001.
Rail terminology is a form of technical terminology. The difference between the American term railroad and the international term railway is the most significant difference in rail terminology. These and other terms have often originated from the parallel development of rail transport systems in different parts of the world. In English-speaking countries outside the United Kingdom, a mixture of US and UK terms may exist.
A rotary snowplow or rotary snowplough is a piece of railroad snow removal equipment with a large circular set of blades on its front end that rotate to cut through the snow on the track ahead of it. The precursor to the rotary snowplow was the wedge snowplow.
A dump truck, known also as a dumping truck, dump trailer, dumper trailer, dump lorry or dumper lorry or a dumper for short, is used for transporting materials for construction as well as coal. A typical dump truck is equipped with an open-box bed, which is hinged at the rear and equipped with hydraulic rams to lift the front, allowing the material in the bed to be deposited ("dumped") on the ground behind the truck at the site of delivery. In the UK, Australia, South Africa and India the term applies to off-road construction plants only and the road vehicle is known as a tip lorry, tipper lorry, tipper truck, tip truck, tip trailer or tipper trailer or simply a tipper.
A railroad crane is a type of crane used on a railroad for one of three primary purposes: freight handling in goods yards, permanent way (PW) maintenance, and accident recovery work. Although the design differs according to the type of work, the basic configuration is similar in all cases: a rotating crane body is mounted on a sturdy chassis fitted with flanged wheels. The body supports the jib and provides all the lifting and operating mechanisms; on larger cranes, an operator's cabin is usually provided. The chassis is fitted with buffing (UK) and/or coupling gear to allow the crane to be moved by a locomotive, although many are also self-propelled to allow limited movement about a work site.
A steam shovel is a large steam-powered excavating machine designed for lifting and moving material such as rock and soil. It is the earliest type of power shovel or excavator. Steam shovels played a major role in public works in the 19th and early 20th century, being key to the construction of railroads and the Panama Canal. The development of simpler, cheaper diesel-powered shovels caused steam shovels to fall out of favor in the 1930s.
A snowplow is a device intended for mounting on a vehicle, used for removing snow and ice from outdoor surfaces, typically those serving transportation purposes. Although this term is often used to refer to vehicles mounting such devices, more accurately they are known as winter service vehicles, especially in areas that regularly receive large amounts of snow every year, or in specific environments such as airfields. In other cases, pickup trucks and front end loaders are outfitted with attachments to fulfill this purpose. Some regions that do not frequently see snow may use graders to remove compacted snow and ice off the streets. Snowplows can also be mounted on rail cars or locomotives to clear railway tracks.
A steam donkey or donkey engine is a steam-powered winch once widely used in logging, mining, maritime, and other industrial applications.
The South Carolina Canal and Rail Road Company was a railroad in South Carolina that operated independently from 1830 to 1844. One of the first railroads in North America to be chartered and constructed, it provided the first steam-powered, scheduled passenger train service in the United States.
Railroads in Honduras were built in late 19th and early 20th centuries by two competing U.S. corporations - United Fruit and Standard Fruit. All were in the Caribbean coastal area and never reached the capital. In 1993, the combined network had 785 km. At present (2006), only three separate segments remain in operation under the management of FNH - Ferrocarril Nacional de Honduras:
Laira T&RSMD is a railway traction and rolling stock maintenance depot situated in Plymouth, Devon, England. The depot is operated by Great Western Railway and is mainly concerned with the overhaul and daily servicing of their fleet of High Speed Trains and also the DMUs used on local services. The depot code "LA" is used to identify rolling stock based there.
The Mauch Chunk and Summit Railroad was a coal-hauling railroad in the mountains of Pennsylvania that operated between 1828 and 1932. It was the first operational railway, in the United States, of any substantial length to carry paying passengers.
Southern Railway 401 is a steam locomotive built in December 1907 by the Baldwin Locomotive Works for Southern Railway. It is a 2-8-0 "Consolidation" type of Southern's "H-4" class.
A train wheel or rail wheel is a type of wheel specially designed for use on railway tracks. The wheel acts as a rolling component, typically press fitted onto an axle and mounted directly on a railway carriage or locomotive, or indirectly on a bogie, also called a truck. The powered wheels under the locomotive are called driving wheels. Wheels are initially cast or forged and then heat-treated to have a specific hardness. New wheels are machined using a lathe to a standardized shape, called a profile, before being installed onto an axle. All wheel profiles are regularly checked to ensure proper interaction between the wheel and the rail. Incorrectly profiled wheels and worn wheels can increase rolling resistance, reduce energy efficiency and may even cause a derailment. The International Union of Railways has defined a standard wheel diameter of 920 mm (36 in), although smaller sizes are used in some rapid transit railway systems and on ro-ro carriages.
The electric railway of the White Knob Copper Co., Ltd. was operated by the White Knob Copper Co. at White Knob near Mackay, Idaho, in connection with its mines, having 7.1 miles (11.4 km) of railroad, two electric locomotives and 40 ore cars. The difference in level over the seven miles was 2,100 feet (640 m), an average of 6 per cent. Eighty tons of ore were handled by each train.
