Note (14 August 2012)
This is a Caldonian Railway type N2 box which opened in 1901. As of 1997, its lever frame contained 96 levers. The frame originally sat nearer the bay window to allow the signalman a clear view along the tracks. The original lever frame was a Stevens GNP of 1901 frame (absolute block working). The locking room windows have been removed and bricked up.
P Kay, 1997; http://www.signalbox.org/gallery/sc/stirlingmiddle.php (retrieved 14-08-2012). Semiphore signals at NS7993 appear to be still in use.
This was visited as part of the improvement of Canmore with reference to signal boxes in ownership of Network Rail and earmarked for significant change over the next 20 years.
