Track Distance Solver

When planning a layout, especially when using a CAD tool to do so, you often times need to find the right combination of tack in order to span a gap. The Track Solver is a simple lookup table for gaps of various lengths, showing which BRIO straight track are needed to create that length. It gives you the most efficient solution, spanning the gap with the fewest track pieces being used. You can adjust the solution by making use of the track equivalences:

  • 1 D = 2 A1 = 4 A2
  • 2 D = 3 A

A few notes about the track solver:

  • With BRIO track you can only build lengths in 18mm increments. Below 270mm, the increments can be as long as 36mm or 54mm.
  • If you have 3rd party track of a non-standard length (such as the Jesse's Toy Box 3" striaght or the Maxim 3" straight) and you want to see if they help, simply subtract the track length of the 3rd party track piece from the needed distance, and look up the new distance on the chart.
  • The Vario System means that "close" is generally "close enough", but short runs of straight track are much less flexible than long runs, and curves are significant;y more flexible than straights.
