Modules

This web page covers the guidelines for the geometric properties of the separable modules.

The modules are a sturdy, and as light as possible, support structure for my model railway. It is constructed from self-supporting ribs of 12 mm plywood. The support structure consists of 3 modules that can be detached for transport in case of moving. The base plates to support the rails are of 9 mm plywood with 4 mm side panels in some places to prevent sagging.

The hidden tracks go through holes in the ribs. For ease of cutting, the holes are round and can be drilled with a circle drill, see below.

This method is only possible with two parallel tracks and if there is enough wood to drill the holes in without weakening the ribs. In all other situations, the hole is made as shown below.
