Remaining Semaphore Signals

Welcome to scot-rail.co.uk, Scotland's online railway community. The group is for any rail enthusiast interested in the railways and trains of Scotland. It not only consists of the wiki that you're reading now, but a busy online forum and mailing list, which was accessible to registered users. From April 2024 the forum has closed, with a replacement started on Groups.io.
This page lists the locations of mechanical semaphore signalling on Network Rail Scotland.

As of September 2024 there are 40 Signal boxes and two ground frames that operate signals with semaphore arms:

Annbank Junction G.F., Arbroath, Auchterarder, Aviemore South G.F., Barrhill, Blackford, Blair Atholl, Carmont, Carnoustie, Craigo, Cupar, Dalwhinnie, Dunkeld, Dunragit, Errol, Fort William Junction, Fouldubs Junction, Girvan, Glenwhilly, Greenloaning, Hilton Junction, Holywood, Huntly, Insch, Inverkeilor, Keith, Kennethmont, Kilkerran, Kingussie, Kirkconnel, Laurencekirk, Leuchars, Longannet, Longforgan, Lugton, Mauchline, Montrose North, New Cumnock, Stanley Junction, Stonehaven, Stranraer, Thornhill.
There are also automatic 'Stone Signals' in the Pass of Brander.
Additionally, Stirling North retains some mechanical disc shunting signals.

Semaphore signals at Arbroath: Down Starting signal AH45 (with lattice post) is clear for the northbound train. To the right of Up Home signal AH15 is miniature arm AH19 for the Goods sidings. Ground disc signals are provided for other shunting moves. Photo by big55012

  • The signals listed below are upper-quadrant stop signals (red arm with vertical white stripe), and on the left side of the track, unless stated.
  • 'Mini' denotes a miniature upper-quadrant arm for a shunt class route.
  • 'Home' denotes a stop signal on the approach to the Signal box; where there is more than one such signal, the outer home is 'Home 1' and the inner home is 'Home 2'.
  • 'Starting' denotes a stop signal (usually) beyond the Signal box, going into the next block section.
  • Signal arms are identified by a 2 letter Signal box prefix, plus the number of the lever that operates it.
  • SIG1 + SIG2 means two signal arms side-by-side on the same structure and read from the same line.
  • SIG1/SIG2 means two signal arms one above the other on the same structure, read from the same line.
With one exception, all mechanical distant signals (yellow arm with black chevron and notched end) have been replaced with colour light signals or reflectorised boards.

The signal boxes below are grouped under Line of Route Codes:
