To clip and scotch a set of railway points (Amer. a switch) uses two pieces of equipment to temporarily lock a set of points into a particular position. [1] The point clip clamps the end of a moving rail (the switch rail ) of a set of points to its associated stock rail , and the scotch is a timber wedge used to ensure that the other moving ...
Spring spikes or elastic rail spikes [25] are used with flat-bottomed rail, baseplates and wooden sleepers. The spring spike holds the rail down and prevents tipping and also secures the baseplate to the sleeper. [26] The Macbeth spike (trade name) is a two-pronged U-shaped staple-like spike bent so that it appears M-shaped when viewed from the ...
D-ATC indicator used on the E233 series trains. The digital ATC system uses the track circuits to detect the presence of a train in the section and then transmits digital data from wayside equipment to the train on the track circuit numbers, the number of clear sections (track circuits) to the next train ahead, and the platform that the train will arrive at.
Pandrol has sold its various products to over 400 railway systems around the world. The company was founded as the Elastic Rail Spike Company (ERS) in London during 1937 to produce and sell an innovative rail fastening developed by the German engineer, Max Rüping.
On straight track, the link and pin coupler is used. Since the vertical curve between the straight track sections and the ramp between the lock chambers has a very small radius, the difference in height would be too great for a link and pin coupler, so the locomotives must be pushed through these sections uncoupled by using the side buffers.
Eventually known as train stops or trip stops, the first mechanical ATS system was installed in France in 1878 with some railroads in Russia following suit using a similar system in 1880. [citation needed] In 1901 Union Switch and Signal Company developed the first North American automatic train stop system for the Boston Elevated Railway.

In 1923 US&S developed the first inductive train control system. (See also pulse code cab signaling.) The company developed coded track circuits, supporting bi-directional cab signaling, in 1934. [4] The first digital rail yard control system was built by US&S in 1970, for the Atchison, Topeka & Santa Fe railway at Kansas City, Kansas. [4]
