'N' Gauge

The previous SDMRS N gauge layout was dominated by a large station taking up most of the scenic area. When the time came to design the current layout it was decided to model much more open countryside - making use of the higher scenery to track ratio that is possible with N gauge. The new design was chosen to allow for the modelling of a mainline running through open countryside and to include a mainline junction station with a branch line diverging to a small country station. At present the layout does not have a name, it is hoped that it will eventually receive one.

Design

The layout is 'U'-shaped and the track plan follows a figure-of-eight shape, bent round to fit into the 'U'. Gentle gradients separate the levels, with the track towards the rear of the layout at a higher level than that at the front. A set of hidden loops, concealed behind the back scene, are included to raise the capacity of the layout, these are monitored with CCTV. The main station, situated on a curve at the higher level across a corner of the clubroom, features through tracks as well a bay platform and run-round for the branch line. The station also has several goods sidings and a loco depot with turntable and engine facility. The branch runs up to a further higher level towards a small country station with passing loop and a bay platform, a small industrial area is also situated here with a siding serving it.

The branchline was remodelled to accomodate a second line and the formation altered slightly to allow for a separate continuous circuit with a new triangular junction included to allow access back to the branch bay platform. The sidings at the branch station are now entered from the opposite end.
