I’ve struggled with solutions for the BRIO #33384 Criss-Cross Track, H2. The challenge is that it’s based on the A track length and the tracks cross at a 45 degree angle. This combination is mathematically problematic, as the angled track cannot make a perfect connection to the main line. Using this track means you’re heavily dependent on the vario system.

As you can see, the issue here is that BRIO opted for symmetry and preservation of the A track length rather than overall fit (a perfect join would require two tracks of unequal length—one 175mm and the other 160mm—and would need to be produced in pairs to allow for more than one orientation).

Making a branch off the mainline is relatively easy. The tightest configuration that produces a decent fit with large curves is 2xA, 3xA3, 2xE.

If you have the space, You can also use A1 along the diagonal and stretch out the main line to give the vario system more to work with.

While making these branches are easy, the real problem is rejoining the main line in a non-trivial configuration. You can, of course, just mirror this configuration end-to-end, but a cross track that rejoins the main line immediately is not particular useful and takes up a lot of space.

A space-efficient solution, and the one I like the best, uses the end of a loop.

All three track lines are perfectly lined up in this configuration. You can stretch out the main loop and the branch along the bottom to produce a non-trivial configuration with room for sidings and accessories. The longer it is, the less you’ll notice the imperfect fit.

The Criss-Cross Track is no longer sold. Most people probably won’t miss it because it’s a pain to use, but if you have one or are able to pick one up used, the above configuration can help you build a clean layout.
