Product Description
This Great Western Railway Gangers key release instrument was used on the Tiverton Branch as part of the G.W.Rs "Economic System of Maintenance" where the Ganger could ask for a release from the signalman on a single line to carry out his duties between trains. This instrument contained a bronze key which gave the ganger permission to occupy the line between the location stated on the key. When the key was withdrawn the single line key token system was locked so no trains could enter the single line. At an agreed time with the signalman the ganger wouldreplace the key in the instrument allowing trains to be signalled again. This instrUment is in working order and is a "B" pattern configuration.
