T-TRAK-N Double Cross Junction r282

Depicted is a Double Cross Junction¹. According to the Unofficial T-TRAK Handbook, this module was designed, but never built, by Brian Heil.² The module is 595 mm (23.5") square and it is 70 mm (2.75") tall. This size conforms to the common corner radii as listed in the Interface Guidelines.

Note that this module, like the T-Junction, requires 597 mm of track. As stated on that page, 597 mm is not a natural Kato track length, therefore it will either require eight extendable track pieces (Kato 20050) or eight custom cut pieces of track for the 79.5 mm remaining track length on both sides of each 90^o crossing pair (assuming 186 mm pieces at the edges as shown)³.

Another track option would be to use 124 mm road crossing tracks (20021) at the edges and cut 186 mm pieces down to 141.5 mm.

3. Technically, one could achieve this track length by using 10 pieces of 45.5 mm, two pieces of 33 mm (90^o crossings), and two pieces of the new 38 mm track.
Length = (5 x 45.5 mm) + 38 mm + (2 x 33 mm) + 38 mm + (5 x 45.5 mm) = 597 mm
However, there would be a lot of track joints and it would be a more expensive solution than cutting a piece of track.
