Knowledge Base

  • According to the Signal Box Register published by Network Rail in February 2013, Carlisle Powerbox was built in 1973 and it contains an 'NX Panel' dating from the same year.
  • When it opened, it replaced "approximately 30 lever boxes on the busy west coast main line so that it now safely controls all the train movements from just north of Carnforth, right up to Kirkpatrick Flemming, twelve miles north of Carlisle. ... it also controls several lines radiating from Carlisle:- North to Annan on the ‘Glasgow & South West’ line, East to Corby Gates on the Newcastle line, West to Wigton on the Cumbria coast line, South to Cotehill on the Settle-Carlisle line. As well as the main line and its “branches” the power signal box is also responsible for both Kingmoor and Upperby goods yards."
  • According to the same article: in 2003 it was operated by just 3 signallers and it also housed the station announcer for Carlisle Citadel Station.

Notes / additional information

The signal boxes that remain standing within the boundaries of the SCRCA can be compared and contrasted via the 'SCRCA Structure Type Definition' page for signal-boxes.

On 5th March 2013, the Network Rail website contained a page entitled "Britain's signalling heritage" which included a link to an Excel spreadsheet listing all of the remaining signal boxes on the NR network as well as those on preserved railways. The URL for the webpages is:

A re-ordered extract from the full spreadsheet (in pdf format), showing the entries for the SCRCA signal boxes (sorted in order of their rail-location), is available here.

Tips: This structure is located approximnately at the centre of the map below at the pointed end of the red marker. To adjust the scale of the map, either click on the [+] and [-] buttons (if Google has displayed these in the top-left corner of the map) or double-click your mouse buttons anywhere in the map area: left button = [+] = zoom-in, right button = [-] = zoom out). To 'pan' (move) the map, hold-down the left mouse button, then move the mouse. To open an information bubble containing brief details of the structure, left-click on the red marker. Please note that the position of the marker is approximate because Google keeps moving the map (yes, really!).
