Track charts showing the location of switches, tunnels, and bridges.
Elevations will be determined once all the plywood sub roadbed is
installed.
The summit will be where it should be - Sand Patch PA.
Some of the tack is not totally accurate due to space, but all the
tunnels are properly located.



Train room dimensions along with the approximate dimensions of the
layout.
The size changed a bit as I was laying out the track. The room is
approximately 755 sqft.
