It is *so* easy to cut the section track with a razor saw. After cutting and de-bur the cut with fine small file or brass wheel brush, use and Xacto knife to clear under the rail for 2 ties back from end (allow rail joiner to go under rail). For the plastic joiner, cut in half, leaving in uncut track.
I have made this module with 220 mm inner track and test the 25 mm rokuhan track, and doesn?t fit, i just have to cut a little MTL flex to fit in there... 18mm...
