Crewe North Junction signal box
Crewe North Junction signal box is signal box with a Westinghouse All Electric Style 'L' lever frame which was commissioned, along with Crewe South Junction signal box, on 29 March 1940 as part of a resignalling project at Crewe railway station. It saw continued use until 19 July 1985 when it was decommissioned for a redesign of Crewe station and its track layout and signalling.
Location
Crewe North Junction signal box is located on the junction to the North of Crewe railway station between the Chester Lines and the West Coast Main Line. The signal box can also see the lines to and from Manchester and Sandbach and all the platforms on the north side of the station. The signal box, still at its original site, is located in Crewe Heritage Centre where there are now demonstrations and simulations of the signalling in the North Junction box by a team of signallers.Design
Crewe North Junction signal box contained a lever frame of the Westinghouse Style 'L' design which was commissioned with Crewe South Junction signal box, which was of the same design. Crewe North Junction signal box was built to a non-standard ARP design, with 15" thick reinforced concrete walls and an 18" thick concrete roof. This was due to it being commissioned in 1940 during World War II so it was built to survive an air raid.Track layout

Staffing
The signal box was staffed by four people: two signalmen, a signal box-lad and a regulator. In the later days it was just the signalmen and the box-lad.Adjacent boxes
Originally there were eight adjacent signal boxes, until November 1958 when Crewe No.3 box and 2 June 1960 when Crewe Station 'B' box was closed. Control of the lines was handed over to Crewe South Junction.Crewe South Junction
Crewe South Junction was a signal box of the same design as North Junction and was commissioned as part of the same project. Absolute block working was operated between Crewe North and South Junctions, with a block bell for each platform to communicate with South Junction. 'Train on line' would be given to South Junction as the train entered the platform as seen from track circuits or visually from the box. 'Out of Section' would be given when South Junction had seen the train leave the platform complete with tail lamp, thus ensuring no part of the train had become uncoupled and left in the platform. Platforms 4, 5 and 6 were 'Up platforms' which meant trains could only be sent 'Up' into those platforms i.e. towards South Junction. Platform 3 was 'bi-directional' so a train could be sent to or from South Junction, meaning there are two block instruments for this platform in both North and South junctions. Platform 2 was 'Down only' and trains could only be sent from South to North. South Junction closed on 2 June 1985, just over a month before Crewe North Junction closed. Signalling was handed over to Crewe Signalling Centre which still exists to this day.The lever frame from Crewe South was preserved and is in use at the Great Cockcrow Railway.
