Kirkallanmuir is a fictional mining and market town situated to the south of Allanton on the eastern edge of the Lanarkshire coalfield. The scenario is that a line was built to it to take out the coal from Allanmuir pit, leaving the Glasgow - Edinburgh via Shotts line at Murdiston. Later the line was continued south to link up with the Climpy extension of the Wilsonton branch from the Edinburgh branch of the CR main line. I have since learned that such a line was once proposed!
The layout was several years in the planning, the final form being somewhat different to what was originally envisaged. The photo below shows a model of the layout made during the planning stage.
To the left are the colliery interchange sidings with the colliery branch disappearing behind them and behind that the main line running along the back of the layout, double track as far as Kirkallanmuir and single beyond. Behind these are a couple of sidings serving the local agricultural merchant and the livestock mart. In the foreground is Allanmuir Kirk and to the right of that the goods yard (on the site of the original terminus). The main line disappears off scene to the island platform station beyond the bridge.
Construction was started in November 2009, this photo showing the baseboards with the Templot track plan glued down.
The overall length is 3 metres on 3 1 metre boards. the slots are to accomodate the train cassettes.
Plain track is all Easitrac , while turnouts are all modeled with interlaced sleepers (as the Caley used in the late 19th century), using pcb sleepers at the crossings and switches with Easitrac sleepers in between.

One of the four pairs of tandem turnouts, this one at the throat of the interchange sidings.
An interesting turnout incorporating two single switch trap points, dividing the two up sidings.
More to follow later.
