Track-bed is done!

All track-beds have been positioned and glued down:

The next steps are to solder all the wires to the tracks and switches, make holes in the platform for all the wires and the moving points of the switches, then glue the tracks!

Since I made the outline of all the tracks, I removed them and I can start installing the track-bed foam.

Track-bed

I am using the Woodland Scenics products:

• Track-Bed strips: https://woodlandscenics.woodlandscenics.com/show/item/ST1461
• Foam Tack glue: https://woodlandscenics.woodlandscenics.com/show/item/ST1444

I'm pretty sure any white glue would do, but I decided to go for peace of mind. The process is fairly easy: put some glue on the plywood, lay the foam, and put some weight for 10 minutes to ensure full contact:

The straight sections are very easy and fast to install:

The curves are a bit tricker. Here's my process. I cut the foam in half along the long side - there is a pre-cut that I follow with a hobby knife. I made some blue marks on a piece of plywood to serve as a gauge: the center mark is the center on the track, the two other blue marks on the side are for the tracks, and the sides of the piece of wood are the bottom of the track-bed.

I then trace the center of the tracks with the blue Sharpie and put pins. These pins will hold the position of the curved track-bed:

The curved sections are actually quite time consuming. Should be done soon ...
