Hi All

Once the final layout size was determined, I then started to design the track layout.

At the initial stages I had decided the the main line curve would be 190mm radius. An arc of this radius was drawn on the front of the baseboard, using a ruler type compass. Templates for the various points were produced, complete with sleeper centrelines, using templot.

The point templates were laid out as shown in the photograph above. This allowed the lengths of the loop and sidings could be checked using actual wagons. I knew that my length of my trains would have to be shorter than on the prototype but I feel that a train of 4 wagons and a brake, in BR days and 5 wagons in independent days would capture the correct feel. The tramway company did not believe in using brake vans, and because it was a tramway the Board of Trade could not force their use!

I had decided early on that I would decrease the distance between parallel lines from the generally accepted 12.5mm between the centrelines. This has the effect in making the layout appear larger than it is to the viewer.

Sidings on the model will have well very severe curves, but the only restriction on the radius of curves was would the wagons go round them without coming off.

The station is a terminus, despite the layout being an oval, the line after the loop and the platform becomes a private siding for the Dairy, and on the prototype there was a baulk bridge over a stream just beyond a white gate. My intention is to include the bridge, but to leave this until I have laid out the loop and sidings.

At this stage the layout was checked to see if the proposed operation sequence would work. Initially I had intended not to have a carriage siding, but the early part of the sequence would have required excessive shunting if the carriages were left in the platform overnight. It is much easier to check the sequence using real rolling stock rather than using paper based methods.

The track in the area where the bridge will be installed is not glued down, but is held in position with screws for ease of removal. Once the track has been removed the baseboard will be able to be cut and carved to represent the stream channel and a link piece will be screwed and glued beneath to maintain baseboard integrity.
