Once all of the cork roadbed was in place, the track was installed using the normal latex caulk as a glue. The mainlines are Peco code 83, and some of the sidings and spurs are Shinohara code 70 from way back when.
The Saturday crew did a splendid job of installing the track switch machines under the layout, saving my back from not having to crawl around on the floor. Great thanks to Brian and Gordie who did most of that awkward underneath work. This is the type of task that really requires multiple people to make it go well, as it really is hard for one person to be in two places at once! Thanks also to Gordie for some of these photos.
While this was going on, Colin and Ken were busy working on installing more fascia back at Carson.
