SOUTH DEVON MODEL RAILWAY SOCIETY

'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.

Setting

The layout is depicted as 1930s/40s Britain but very often modern &/or foreign rolling stock appears.
