KEYHAM STATION SIGNAL BOX
When the Cornwall Railway Company constructed the original railway line through Keyham it was only a single track so the Company only had to provide a simple junction into the Royal Dockyard controlled from Keyham Junction Signal Box.
Following the doubling of the main line by the Great Western Railway Company in 1899, a more complicated junction was created and it was also proposed to erect a railway station at Keyham for the benefit of the men from the Royal Naval Barracks. So on Monday June 25th 1900 Keyham Junction Signal Box, along with the Keyham Viaduct Temporary Signal Box, were closed and a new Keyham Station Signal Box opened. The new double track main line was also brought into use on that day. The Signal Box had a frame of 33 levers but only 25 were needed at that time. Keyham Station was opened to passenger and goods traffic on Sunday July 1st 1900.
In about 1937 the Up Back Platform line was extended at the Devonport end to enable a train of up to 49 wagons to be stabled there. This enlarged the Signal Box frame to 59 levers, although some were still not used. This was followed in May 1941 by the addition of a new connection to the Royal Dockyard for Southern Railway traffic that eventually resulted in 53 levers being in use with 6 spares. The connection was removed in 1956.
No further goods traffic was taken at Keyham from Monday July 19th 1965 but the goods shed line was not taken out of use until Friday April 22nd 1966.
With the introduction of Multiple Aspect Signalling in the Plymouth area in November 1960, Keyham Station Signal Box became the westerly fringe box for the Plymouth Panel Box and the Up Advanced Starting Signal beyond the Royal Navy Avenue road bridge was changed to colour light and made an Intermediate Block Post working independently of the Keyham Station Signal Box.
Finally Keyham Station
Signal Box was closed as from Monday July 2nd 1973 when its signals and
points were amalgamated into the Plymouth Power Box network although a few
points were left to be controlled from new East and West Ground Frames.
