I had a free afternoon today so I hauled a sheet of 3/4″ plywood into the trainment and cut my first roadbed.
I installed a “?”-shaped piece (without the dot) that takes the mainline through the Lynn Valley. The location of this piece is critical since it must connect St. Williams and Port Rowan without hitting any of the intervening walls.

Here’s another view, this time looking across the future location of one of the bridges in the Lynn Valley. Port Rowan is to the right:
Obviously I will need to cut away the roadbed when the bridges are ready to be installed.
