A buffer stop, bumper, bumping post, bumper block or stopblock (US), is a device to prevent railway vehicles from going past the end of a physical section of track. The design of the buffer stop is dependent, in part, on the kind of couplings that the railway uses, since the coupling gear is the first part of the vehicle that the buffer stop ...
The centre of the buffer on European railway vehicles must be between 940 and 1,065 mm above the top of rail. Spain was an exception for a long time. A buffer separation of 1,950 mm was specified there because of the force transmitted to the longitudinal beams of the wagons, which are further apart due to their broad gauge railways.
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.
A signal with associated trip arm in the raised position (circled) Part of a railway signalling system, a train stop, trip stop or tripcock (sometimes called a tripper) is a train protection device that automatically stops a train if it attempts to pass a signal when the signal aspect and operating rules prohibit such movement, or (in some applications) if it attempts to pass at an excessive ...
Trap points with a crossing are double trap points where the tongues of rail are longer, so that the trap point rail nearest the main line continues over the siding rail with a common crossing or frog. A trap road with stops is a short dead-end siding leading to some method of stopping a vehicle, such as a sand drag or buffer stop.
On a few light rail lines IIATS has been employed in a manner similar to mechanical train stops, stopping the train if it passes an absolute stop signal. It is useful where light rail shares tracks with mainline railroad trains as mechanical trips may be damaged by or interfere with freight operations and because light rail vehicles can be ...

The Old Colony Railroad and its branches were acquired by the New York, New Haven and Hartford Railroad in 1893. [ 5 ] When the Boston Elevated Railway (BERy) was first constructing its rapid transit Cambridge–Dorchester line in the early 1910s, plans called for the line to be extended south from Andrew to Codman Square via Edward Everett ...
