These pages are very much under construction - which is fine because my On30 layout is only in the planning stages anyway.
The layout will be small, fitting into a 9'6" wall in my train room (shed, really) alongside the existing HOn30 Dutton Bay Tramway. At some time in the future a decision will need to be made regarding expansion, At that time I guess I have to choose between the two scales. The DBT Permanent Track Plan page shows how the two layouts will fit into the available space.
