A Railway Shock Absorber, Railway buffer stop, bumper, bumping post, bumper block or stopblock, is a device to prevent railway vehicles from going past the end of a physical section of track.
The design of the railway buffer 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 touches.
ARC dampers design and manufacture railway buffers through our latest hydraulic technology which can significantly reduce the buffer size.
On 28 June 2015 – Mumbai, India – A local train crashed into a buffer on platform no. 3 of Churchgate station in Mumbai. 6 people were injured in the accident.
The hydraulic buffer used to slow the impact did not function and the train overshot the platform.
Current obsolete design of railway buffers installed in India are not equipped enough to provide safety to new era express tranins with high speed. At ARC, we design buffers
and hydraulic dampers which can safely decelerate extreme masses at high speeds.
