Thanks for the kudos. It took me about a year to build it. Its Tomy AFX track soldered, and moulded to a one piece track similar to a routed track. I run a trakmate freeware program on an old Dell windows 95 desktop computer for a lap timer. My grandstand needs more HO scale people, and I need some food stands and Porto potties lol. I have seen those autoworld drag race sets. Those are really cool. My father in law lives out in D/FW area.
