September S&T Report,
By Robert Law,
Yet another mouth has passed with more work been completed around the railway within the S&T department. Some time has been spent at Aviemore Speyside box, trying to improve the wight on the points into the carriage shed and the engine shed. With the carriage shed points it was found that there was an in balance of the rodding between the signal box and the A end of the points. With a new closure cut and bolted into the rodding run. This has greatly improved the wight of the point. Hopefully keeping our signallers happy.

At Boat of Garten North cabin the new points and signals are all working very well with only a few minor adjustments been required as everything beds in. The scaffolding is down around the signal box with just a few little bit still requiring attention with the building but there should be a separate report shortly about that.

With the project on hold at Boat of Garten North box, until the location cases arrive. Attention has moved onto the long awaited Key token machines between Boat of Garten and Aviemore Speyside. Over the years the work has been on and off with this project. The large jobs that have been done over the years, is the repairs to the pole route between Boat and Aviemore. There is still lots to be done to the pole route. With at least 3 poles requiring replacement, trees needing cleared from underneath the wires. Plus lots of cross members on the poles require replacement. Considering the vast majority of the poles date back to the 1950’s and earlier (it is believed), we can not complain to much. Before lock down began a new cable was run from the end of the pole route at Aviemore to Speyside box. Completing the connection between the two signal boxes.

The machine themselves are Tyers number 9 machines. Both machines in there recent past have been to uni part rail to be professionally overhauled. The locks have been reconfigured to an A lock, (the type of keys that we will be using). The machines are now in place at Aviemore and Boat of Garten. They have been tested by the installer, although are still requiring to be independently tested to prove that installation has been done correctly. We are waiting on personnel bodies for this task. The keys you can see sitting in the machine are not the key that will be used once the machines are in use. They are for test purposes only.

Included within the introduction of the key token machines between Boat of Garten and Aviemore. The section Token key and locking requires to be changed between Boat of Garten and Broomhill. The Broomhill section token will become the token that opens up Boat of Garten Signal boxes. Resulting in the locks requiring replacement and a new section key being created. Hear you can see the trial fitting of the new lock on Broomhill loop GF. The original one is back on until such time that we are ready to do the change over.
