Turnouts facing and trailing. Note that this diagram is for left-hand traffic; for right-hand traffic, "F" and "T" would be swapped. Facing or trailing are railway turnouts (or 'points' in the UK) in respect to whether they are divergent or convergent. When a train traverses a turnout in a facing direction, it may diverge onto either of the two ...
A right-hand railroad switch with point indicator pointing to right Animated diagram of a right-hand railroad switch. Rail track A divides into two: track B (the straight track) and track C (the diverging track); note that the green line represents direction of travel only, the black lines represent fixed portions of track, and the red lines depict the moving components.
Double junction, or level junction (left hand running). A double junction is a railway junction where a double-track railway splits into two double track lines. Usually, one line is the main line and carries traffic through the junction at normal speed, while the other track is a branch line that carries traffic through the junction at reduced speed.
A single tongue trap consists of only one switch rail, leading away from the main line to a short tongue of rail. This is usually placed in the rail farthest from the main line. Double trap points are a full turnout, leading to two tongues. Usually the tongue nearer the main line is longer than the other.
Consider a railway with two block sections as in the diagram. Section 1 has frequency A injected at the left-hand end and received at the right-hand end. Section 2 continues from the right hand end of section 1 where frequency B is injected and then received at the right-hand end of section 2. Track circuited railway with two block sections
This template is the parent template of the Railway accidents and incidents in xxxx templates, and should not be transcluded directly into articles; its child templates should. A child template for a given year, for example {{Railway accidents and incidents in 2010}}, has the following structure:
Some form of ATS or ATC is required on all U.S. rail lines that operate at 80 mph (130 km/h) or more. In the 1990s, communication-based train control (CBTC) systems started to be used in rail transit systems. These systems utilize radio communications between train and wayside equipment to perform the functions of the signaling system.
The first report identified 2,363 stations and 5,000 miles (8,000 km) of railway line for closure, amounting to 55% of stations, 30% of route miles, and the loss of 67,700 British Rail jobs, [1] with an objective of stemming the large losses being incurred during a period of increasing competition from road transport and reducing the rail ...
