The Golden Valley Light railway

A 2ft (610mm) Narrow Gauge Railway in Derbyshire


Air Braking System for passenger trains
- design, installation and operation


The GVLR uses a single pipe automatic continuous air brake system for its passenger trains. This is required in order to provide rapid stopping and safe control of speed on the long downhill sections of the railway while maintaining efficient working.

Commercial vehicle components are used wherever possible for economy. A download with a full description of the system is available including how a Westinghouse steam powered air brake compressor pump operates.
