This buffer stop at Zurich HB in Switzerland is designed to move up to 7 metres (23 ft) to slow down an 850-tonne (840-long-ton; 940-short-ton) passenger train from 15 km/h (9.3 mph) without damaging the train or injuring passengers. A buffer stop, bumper, bumping post, bumper block or stopblock (US), is a device to prevent railway vehicles ...
The Montparnasse derailment occurred at 16:00 on 22 October 1895 when the Granville–Paris Express overran the buffer stop at its Gare Montparnasse terminus. With the train several minutes late and the driver trying to make up for lost time, it approached the station too fast and the driver's application of the train air brake was ineffective.
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.
A railway ending in a locality (terminus) with no other rail services. Typically includes buffer stops at the end of the tracks. The opposite of rail crossing Dead man's handle A safety mechanism on a train controller that automatically applies the brake if the driver releases the handle. It is intended to stop a train if the driver is ...
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.
A track circuit interrupter may be fitted at catch points, trap points or buffer stops to maintain a track circuit in the 'occupied' state in the event of a derailment. The track circuit remains de-energised until the interrupter is replaced.
Currently, the rail authority projects its full 500-mile system will cost $105 billion. When voters approved bonds in 2008 to build the high-speed-rail system, total cost was estimated at $33 billion.
[4] [5] The train crashed through the buffer stop, then through the stationmaster's office, and then demolished a newsstand. [6] The locomotive began skidding to its right. [1] It also destroyed a steel pillar in the concourse, and tore through the concourse's concrete floor (which was 6 inches (15 cm) higher than the tracks outside). [5]
