Laying track

When I started my layout I layed the track, used cork board tacks to hold it in place and traced the layout. Then I pulled up the track and installed the cork. That's the simple version. I use a 1/2" plywood "shim" under my track to add more depth for the scenery, it's 3 1/4" wide. Then I pit down the cork. This gives you a more 3D area to model diches or streams or whatever.

Lancer, if you are only using a "four pieces of lightly bent flex track," go ahead and lay the track and trace it; then, come back and lay the cork.  If you were using much more flex track, I'd have recommended laying the cork as the flex track was laid; it's easier to make the cork fit the flex track as its laid, than making the flex track conform to the pre-installed cork IMHO.

Yes, what you are looking for is a way to mark the centerline of the track, some place to line the cork up with.
