Railway signal
Responsibility for the signalling at the station is divided between Preston PSB (main line) and the surviving manual ex-Furness Railway signal box at Carnforth Station Junction, sited just past the junction between the Barrow &amp; Leeds lines. This has acted as the 'fringe' box to the PSB since the main line was resignalled in 1972/3. Two other boxes (F&amp;M Junction &amp; East Junction) were closed and demolished when the northern side of the triangle (avoiding the station) was decommissioned in 1998.
