This was built in 1925 when it was known as Exeter Queen Street C Signal Box; it became the B signal box in 1927 and the station was renamed in 1933. It has not been used for signalling since 1970. Français&#160;: L'ancien poste d'aiguillage B, dans la gare centrale d'Exeter, dans le comté du Devon en Angleterre. Construit en 1925 sous la dénomination de poste d'aiguillage C de la gare de Queen Street, il devint le poste B en 1927 et la gare fut renommée en 1933.

context_page_description: Exeter Central railway station is the most central of the stations in the city of Exeter, Devon, United Kingdom. It is 171 miles 30 chains down the line from London Waterloo. The station is smaller than Exeter St Davids on the west side of the city.
  Great Western Railway manage the station and operate trains on the routes to Barnstaple, Paignton, Exmouth. South Western Railway run trains between St David's and London Waterloo via Exeter Central.
  From 1860, when it opened by the London and South Western Railway, until 1933, when it was rebuilt, it was known as Exeter Queen Street.
context_section_description: In the 1860s there was just a single track to the East but two tracks to the West; all the points and signals were operated on the ground. The first signal boxes were brought into use in 1875 when three controlled the extensive layout: 'Queen Street A' and 'Queen Street B' at the east end of the station, with 'Queen Street C' situated at the west end between the two platforms. These signal boxes were all closed in the 1920s. The C box was replaced by a new one at the west end of the eastbound platform on 13 September 1925. The A and B boxes were replaced by a new, larger box on the north side of the line beyond the New North Road bridge on 15 November 1927. This was named 'Queen Street A' and the C box was renamed 'Queen Street B'; six years later they were renamed again as 'Exeter Central A' and 'Exeter Central B'.
  The B box was closed on 23 February 1970 and the A box was then renamed just 'Exeter Central'. This too closed on 6 May 1985 when control was transferred to the new panel signal box at St David's. With this change came resignalling; the westbound platform 2 was signalled for trains to run in either direction as was the westbound line to St David's. The signals are interlocked so that trains cannot start from either St David's or Central until their route is clear right through to their platform at the other station; a feature replicated from the days of steam locomotives with less power or brakes than today's diesels when it was undesirable for trains to come to a stand on this steeply graded section of line.
