All the visible track on the 1900 era layout is code 70 and 55 handlaid on wood ties. The exception
being a couple yard tracks that are code 55 on PC ties. The switches are built on paper templates made from P&R
switch diagrams drawn in 1905. The diagrams range from #3 to #14 switches. I am using mostly #5 switches with
some #6's on sidings and crossovers and a few #4's in industry tracks.
