Change of view
The next item to improve the view on Kyle of Sutherland will be an LMS bracket signal, replacing the current single tubular post signal. From 1935 or so, the LMS changed from cranks and wire to a rocking or torsion bar to transfer the signal operation from the main post to the doll on bracket signals.
This upside down view of the landing shows the rocking bar between the trimmers. The far crank is operated by wire from the trackside crank, and the near crank operates the wire to the signal arm. Clearances are tight, and the rocking bar just fouls the doll post, which will need a wee nick between the post support plates (only one so far to ease assembly).
So now it’s on with the signal arm and all those tricky fittings.
