We are good at re-using stuff at the GLR - no doubt about that! One only has to look at the signals for a start. We do phones as well, and having been presented with a whole bunch of redundant SPT's (Signal Post Telephones) from the Seaton Tramway, where they had been re-used from the 'Big' railway and rebuilt and re-wired to their own requirements, Gradually over the years I have been rebuilding them. Feeling a bit off-colour today I decided not to go to the GLR but spent the day on and off in the garage doing major surgery on this one. I've removed the dial that I had previously put in as it will now be 'Hot-lined' to Common Lane Signal Box. Here it is during the operation (which of course took much longer than anticipated). Fellow telephone anoraks will, I'm sure, note the use of a PCB (Printed Circuit Board) from a Tele 2/722, better known to normal people as a 'Trimphone'.

The Gartell Light Railway is a privately run narrow gauge edutainment railway located at Yenston, south of Templecombe, in Somerset, England. It operates a 2 ft (610 mm) narrow gauge railway running for 3⁄4 mile (1.2 km), partly along the track of the old Somerset and Dorset Joint Railway.The railway has 4 stations - Common Lane, Pinesway Junction, Park Lane and Tower View. The railway is controlled using a comprehensive signalling system operated from two signalboxes - Common lane and Pinesway Junction. Both signalboxes control a mix of semaphore and colour light signals with mechanically operated points. The railway is open to the public on selected dates through the year when it normally operates an intensive 3 train operation with departures from Common Lane station every 20 minutes through the day between 1030 and 1630.
