The line between Shrewsbury and Wolverhampton was opened as a through route in November 1849. Cosford station was opened much later than other stations on the line when the decision was taken to site an RAF base there just before the start of the Second World War. Originally the station was known as Cosford Aerodrome Halt, but due to wartime security concerns, this was shortened to just Cosford in 1940. Trains originally ran to Wolverhampton Low Level and the GWR main line to eastbound, but were diverted to Wolverhampton High Level and the ex-LNWR Stour Valley line to Birmingham New Street in 1967.
2011-12 reconstruction
The station was closed to passengers from 29 October 2011 until 30 April 2012. Costing £2.1 million Network Rail replaced the wooden 1937 station buildings as well as the platforms, which were constructed from century-old wood railway sleepers with the new platforms made from glass reinforced polymer, and the stairs leading up to them. Its re-opening was delayed by 5 weeks. The redevelopment has been criticised for a lack of disabled access.
Signal box
The most recent Cosford signal box stood a little to the west of the station. As well as forming a block post this signal box controlled entrance and exit to up and down refuge loops and the previous rail connection into the adjacent RAF site from the up refuge loop. It has been abolished as a result of the 2006 resignalling scheme with control passing to Madeley Junction. Much of the redundant signalling equipment has been distributed to various heritage railways, the Gloucestershire Warwickshire Railway is believed to have received the majority. This structure is thought to have been the last signal box constructed by the Great Western Railway in Shropshire. Much of the contents and structure of this 1939 constructed signalbox has been salvaged for reuse on another heritage railway. The remaining brickwork was demolished in the small hours of Sunday 21 October 2007. Remarkably, the signalman's portacabin style privy remains in-situ as of late August 2008. The advent of longer trains destined for Ironbridge Power Station has resulted in much reduced used of the refuge loops as they are too short to accommodate the length of today's coal trains.
Services
There is a basic hourly off-peak service in each direction, westbound to and eastbound to and Birmingham New Street run by West Midlands Trains. Additional trains call at peak periods.
