Hi Dave,
The Sundance Central Modular is comprised of three types of modules which are straight, transition and curved modules. The straight and transition modules are 30" wide x 60" long and the curved module is in the shape of a pentagon with the two side 30" wide to allow connection to the other modules. The radius of the inside track is 66" (5'-6") and the outside is 78" (6'-6").
The first track centerline is 6" from the face of the module and the second track is 8-1/2" centerline to centerline from the first track. Since our modular was started four years ago and since we run 1:20.3 equipment, we want to have clearance betwwen the two tracks to allow the large K models to clear each other.
The basic module with 2" thick extruded foam base within a 1" x 4" perimeter wood frame and the two tracks attached weight only 11 lbs.
If you would like to see more information about our modular construction, we have a dvd video available for purchase on our web site at

Dean and Joe: It was my pleasure meeting and talking to you both in person at the Big Train Show and thanks for all your wonderful comments about our modular.
