S&T progress at Aviemore (re-worded) - 16/17 March 2019

Another busy weekend for the Signalling and Telegraph Team (S&T) at the Aviemore South Ground Frame. They suffered similar weather to the PWay Squad on the Saturday at the Summit but we don't have any pictures to record how bad it was!
 
 
Georgie was on site on Saturday afternoon with Nathan as the loop points were needing a bit of heat treatment as they were not quite up to S&T Departmental exacting standards. This was done successfully and switch rail now closes satisfactorily against the stock rail.
 
 The new Signal at Aviemore Station worked by Number 5 lever on the Station South Ground Frame has been wired up to interface with Network Rail. The group involved with this were Daniel Nimmo, Dave Bird, Mike Insch, Dave Dow and Rob Law all shown in the photo beside the ground frame and under Stephen Muirhead’s supervision
 
The ground works for new signalling cables and the telephone cable for direct communication with the NR Signaller at Inverness have been completed. The fitting of the phone and termination of the cable will be carried out by Siemens. You can see the concrete base for the phone to the right of the ground frame.
Following completion of the work on Saturday we were able to start setting up the detection of 7 points, for the new signal. This signal is route selected by means of the floating wheel assembly visible in the foreground below.


 
The circuit controllers on number 4 lever, which works the ‘additional control’ (also known as a ‘slot’) on the NR signal coming from the South and number 5 lever which works our signal has been fitted by the team, while Rob Law installed the interconnecting cables between the NR disconnection box, the Strathspey apparatus case, the signal and the Ground Frame.
