It is a Midland Railway signal box dating from 1899, although the original mechanical lever frame has been replaced by electrical switches. Seen here in 2009. Seen here in 2009. On a rail transport system, signalling control is the process by which control is exercised over train movements by way of railway signals and block systems to ensure ...
Gas lighting was replaced by fluorescent electric lights in 1960. [12] Bristol Panel Signal Box was built on the site of Platform 14. When opened, it controlled 280 multiple-aspect signals and 243 motor-worked points on 114 miles (183 km) of route, the largest area controlled by a single signal box on British Rail at the time. [16]
