Overbuffering
In railway operations, overbuffering refers to the pushing of the buffers of two railway vehicles one behind the other on the inside of the arch.
Overbuffering can occur due to the high speed of trains, when shunting or in operation and when driving on tracks with an extremely small radius (less than 100 m). It can lead to derailment . The EBO stipulates that vehicles must be equipped with buffers for curved tracks ≥ 150 m. The radius of curves in new buildings must not be less than 180 m.
Too short a straight line between two opposing arcs can also cause overbuffering. Another reason for overbuffering can be incorrect coupling or a defective buffer.
