Tie Crane
A tie crane or tie handler, is a piece of rail transport maintenance of way equipment used to move and handle the railroad ties (also known as sleepers) used in rail tracks using track relaying. The machines are used as an alternative to the manual labor once used. Tie cranes frequently work with tie extractor/inserters to replace ties as part of a section gang. History Tie cranes were developed to speed up and automate the labor-intensive task of moving railroad ties, which typically weigh over 100 pounds (and as much as 500 pounds for concrete ties). Before tie cranes, track workers would move ties by hand, using tools such as tie tongs and lots of muscle. The tie crane allows one operator to move ties far faster than a group of track workers could move by hand. Design The central feature of a tie crane is, of course, a crane. This crane extends the reach of the vehicle up to 25 feet from the tracks. It is used to move ties into position for other machines to insert into th ...

Rail Transport
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles ( rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maintenance Of Way
Maintenance of way (commonly abbreviated to MOW) refers to the maintenance, construction, and improvement of rail infrastructure, including Railway track, tracks, ballast, grade, and lineside infrastructure such as Railway signal, signals and signs. Track The most fundamental maintenance of way task is the construction, repair, and replacement of the track and its supporting ballast and grade. The task was once done entirely by manual labor, but in the 21st century, track maintenance is largely done by specialized machines that are much faster and require fewer people to accomplish the same amount of work. Electrification systems On rail lines, which include electrification by a third rail or an overhead line, maintenance of way work includes repairing and replacing the systems.

Railroad Tie
A railroad tie, crosstie (American English), railway tie (Canadian English) or railway sleeper (Australian and British English) is a rectangular support for the rails in railroad tracks. Generally laid perpendicular to the rails, ties transfer loads to the track ballast and subgrade, hold the rails upright and keep them spaced to the correct gauge. Railroad ties are traditionally made of wood, but prestressed concrete is now also widely used, especially in Europe and Asia. Steel ties are common on secondary lines in the UK; plastic composite ties are also employed, although far less than wood or concrete. As of January 2008, the approximate market share in North America for traditional and wood ties was 91.5%, the remainder being concrete, steel, azobé (red ironwood) and plastic composite. Tie spacing may depend on the type of tie, traffic loads and other requirements, for example 2640 concrete ties per mile on North American mainline railroads to 2112 timber ties per mile ...

Rail Tracks
A railway track (British English and UIC terminology) or railroad track (American English), also known as permanent way or simply track, is the structure on a railway or railroad consisting of the rails, fasteners, railroad ties (sleepers, British English) and ballast (or slab track), plus the underlying subgrade. It enables trains to move by providing a dependable surface for their wheels to roll upon. Early tracks were constructed with wooden or cast iron rails, and wooden or stone sleepers; since the 1870s, rails have almost universally been made from steel. Historical development The first railway in Britain was the Wollaton Wagonway, built in 1603 between Wollaton and Strelley in Nottinghamshire. It used wooden rails and was the first of around 50 wooden-railed tramways built over the next 164 years. These early wooden tramways typically used rails of oak or beech, attached to wooden sleepers with iron or wooden nails. Gravel or small stones were packed around the s ...

Tie Extractor/inserter
A Tie exchanger (also known as a TKO for Tie Knock Out, or by various combinations of tie exchanger, extractor, replacer, or inserter) is a self-propelled railroad maintenance of way vehicle that removes old railroad ties (also known as sleepers) from tracks and inserts new ones. By using mechanical and hydraulic force, a tie extractor/inserter can replace ties much faster and with more precision than is possible by hand. The TKO is distinct from the track renewal train, a much more complex machine which replaces the entirety of the rails and ties at once. History While wooden railroad ties are treated with preservatives such as creosote to resist decay, they do not last forever and must be replaced every 20 to 40 years, depending on factors such as climate and the type of wood used. In particularly wet climates, replacement must occur more frequently as the ties rot faster. Ties may also need to be replaced regardless of age after derailments, washouts, or other events that cau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Road–rail Vehicle
A road–rail vehicle or a rail–road vehicle is a dual-mode vehicle which can operate both on rail tracks and roads. They are also known as two-way vehicles (german: Zweiwegefahrzeug), hi-rail (from ''highway'' and ''railway'', or variations such as high-rail, HiRail, Hy-rail), and rail and road vehicles. They are often converted road vehicles, keeping their normal wheels with rubber tires, but fitted with additional flanged steel wheels for running on rails. Propulsion is typically through the conventional tires, the flanged wheels being free-rolling, used to keep the vehicle on the rails; the rail wheels are raised and lowered as needed. There are also purpose-built road–rail vehicles. In case of jeep trains, road wheels are directly replaced with railway wheels. Vehicles with tires need special areas like level crossings to change modes. A vehicle on caterpillar tracks rather than road wheels, which allows mode change anywhere without the need to use a level crossing ...
