O14 Trackwork is not readily available and dual gauge O / O14 even less so!
So all trackwork is handbuilt using soldred construction on copper clad sleepers. Code 100 rail has been used on the Dual gauge to represent a light 60LBS rail. The narrow gauge uses code 83 at the back and code 75 at the front. Why 2 different codes for the narrow gauge ? Well I had some code 83 left from a previous project and it matched the wagon turntable. The code 75 was the new purchase.

Points are operated by servo's using MERG servo control boards. The blades are lose heal, and given the tight radius this is prototypical. Each point blade has 0.9mm brass wire at the heal forming the pivot. 1mm brass tube is inset into the baseboards to act as the bearing.
A 0.7 mm dropper at the toe of each blade passes through the baseboard into a terminal block which is in turn connected to the servo.
