AutochockAddressing the stretcher bar problem

The stretcher bar problem

Many railway points around the world use stretcher bars to maintain gauge through the points.

Stretcher bar failures have been implicated in the Potters Bar and Greyrigg derailments as well as other devastating accidents worldwide.

Attempts to improve the design of these components and enhance safety have fallen short of a solution – until now.

Autochock provides a failsafe interlock which can be retrofitted to existing points – simply and in minutes.
