Eggesford signalling

Nicks workshop mutterings

I have now got around to reinstalling the signals on Eggesford. The late Jeremy Dixon had fully working signals using hand made controls. These consisted of a magnet attached to a small length of brass tube whic was made to slide up and down via a crank attached to an old Triangle TT point motor;


A fairly crude but very effective mechanism. The end of the operating wire from the signal has a soft iron end which is attracted by the magnet when it drops and is pushed up when it rises.

I have removed the old solenoid and replaced it with a servo which is operated by Heathcote servo boards;


The operating wire for the servo board is fed back to the locking lever frame and we now have fully interlocked points and signals. Below shows. The UP stater in situ with the DOWN inner home in the distance.
