The RCCS features nearly limitless coaster circuit design flexibility. There are literally hundreds of designs possible with the parts included in the base set alone. A visit to the local specialty toy, hobby, or train shop for more of our growing line of accessories expands the creative boundaries even further. The RCCS is also intuitive and easy to assemble, alter and disassemble. Though creatively challenging, the large blocks of required assembly time and resultant frustration common to many other construction sets are noticeably absent.
