Baseboard construction

The attraction of strong/durable but light baseboard units has focussed my attention on the advantages of a sectional aluminium construction rather than a traditional plywood and timber approach. The sloping valley sides and railway bridge over river nature of the proposed layout suggest a widely varying topography for which a minimal aluminium skeleton might offer the widest range of scenic options. However, P4 finescale demands very high standards of track alignment and construction in order to deliver flawless train operation, so the challenge is there. A principle baseboard width of 2ft will allow the boards to pass easily through doorways,whilst, 4ft or 6ft max lengths will make transportation to exhibitions more viable. The precision locating dowels from the EM gauge society are perfect for locating each board in relation to its neighbour and will be my method of choice. I would like a mean baseboard height of around 3ft for the valley floor so as to alter the viewing perspective of the onlookers i.e. looking down into the valley. The format will be a 'Y' shaped version of an 'end to end' layout with an approximate 8ft x 16ft centrally located scenic section to give more depth and flexibility. The 3 fiddle yard/storage sections will be 2ft by 12ft.
