I'm reusing some of the track & benchwork from my Little Le Mans layout. It was a job scraping off the scenery residue (including a sand trap!) from the old layout but I'm cheap & believe in recycling so I guess it was worth it.
Yes, I know it's butt ugly at this point. Trust me, it will look decent by the time I am done.

I used track clips at every joint & found that the Tomy clips would also work to attach the two tracks side by side as long as I added a 1/4" styrene shim.

A very preliminary test run tells me that I'm going to have to do a little work on the inside lane of the banked oval. The pickups of the Mega G's snag on the rails at the joints. Anyone have a simple fix? I'm thinking of dremeling the points of the rails down a hair where the shoes catch.
I'm going to do a build log on this so stay tuned if you like that sort of thing.
