Local door operation refers to a procedure and system in place on railway rolling stock on the United Kingdom railway network. It is where a single door on a train is operated by its train crew from a crew operated switch, often on a train door control panel operated by the train's guard. This differs from the Emergency Door Release or Egress ...
A passing loop (UK usage) or passing siding (North America) (also called a crossing loop, crossing place, refuge loop or, colloquially, a hole) is a place on a single line railway or tramway, often located at or near a station, where trains or trams travelling in opposite directions can pass each other.

Selective door operation is implemented at certain railway stations in the United States. In the New York City Subway, the 6 + 1 ⁄ 2-car-long platforms at 145th Street (and formerly the 5-car-long loop platforms at South Ferry) are too short to accommodate full-length trains of ten 51.4-foot-long (15.7 m) cars, so only the first five cars of the train opened their doors at these stations.
Most crossing loops are not regarded as double-track even though they consist of multiple tracks. If the crossing loop is long enough to hold several trains, and to allow opposing trains to cross without slowing down or stopping, then that may be regarded as double-track. A more modern British term for such a layout is an extended loop.
Railway engineering is a multi-faceted engineering discipline dealing with the design, construction and operation of all types of rail transport systems. It encompasses a wide range of engineering disciplines, including civil engineering, computer engineering, electrical engineering, mechanical engineering, industrial engineering and production engineering.
In 1895, the Railway Signaling Club was organized at a meeting in Chicago, Illinois, and created a code of rules governing the operation of interlockings. In 1919, the Signaling Club became the Signal Division of the newly created American Railway Association (ARA) and the Telegraph Superintendents became its Telegraph and Telephone Section.
CTC consolidates train routing decisions that were previously carried out by local signal operators or the train crews themselves. The system consists of a centralized train dispatcher's office that controls railroad interlockings and traffic flows in portions of the rail system designated as CTC territory. One hallmark of CTC is a control ...
The design ultimately derives from stiles of stone slats placed to facilitate human passage over pits that developed on public footpaths in Britain, a practice that predates Roman times. [16] In the early 2000s a British manufacturer of rail crossing equipment, Rosehill Rail, worked with Network to develop the modern rubber anti-trespass panel ...
