This has been - and remains - an extended process. Once there was a robust design, I constructed the baseboards quite quickly. Track laying followed much more slowly and methodically, and the early wiring was even slower. Once I had a routine in place I was able to speed up, and the fiddle yard - technically the most complex section - was completed in a fortnight.
This section provides background to the "mechanical" side of the layout. There is nothing clever or original in the way this has been approached!
