Mckenzie are builders of interlocking frames and brass HO scale signals.

Our interlocking frames are available in 3 flavours;

Mckenzie Style (A Pattern - Victorian) and a NSW Style that can also be used for some British Railways

We also build ground frames, these are a smaller frame in size and are for use where 1 or 2 points are controlled.

**please note that these smaller frames are limited in the number of levers **

Victorian somersault semaphore signals and colour lights.

as well as NSW lower quadrant semaphore signals can be built to order.
