Can you make a Rokuhan X layout without a flyover using a R025 and 220mm radius curved track for a test layout?? I tried using the SCRAM software, no luck. Current length straight track leaves a gap at the crossover.

Roadbed track allows for flexibility in the joint so there is no issue or gap when you really build the plan. The way I deal with gap issue in the software is I build outward from the crossover, and let the gaps show up at the center of the curves. The gap is a little less unsightly out on the edges than at the center. If the gap is positive, you can join it with flex track knowing that those little pieces wont be used on the real thing.

Only way I could get SCARM to follow the Rokuhan instructions and not leave gaps is interjecting a couple of the next larger radius and/or adding a 25mm straight. Generally, have to add the next larger radius section to the end of the straight sections off the R025 crossing. I played with SCARM a little tonight and can try to upload the layouts I came up with. There are three versions built in the file. Attachments:doublecross exp.scarm (16.65 KB)

For an approximately 220-245mm radius curves with no gaps in the software, try this:
Place the crossing in the center. Place the 4 220mm straight sections, one on each connection point of the crossing, making the "X". Then build the Curves, alternating R220-45°, R245-30°, R220-45°, in that order, off of each arm of the "X". Then place a final R245-30° in the center of the curve. The gaps should be minimal and the software should auto-connect both side of the last section.

This looks like one of those solutions that may well work in practice but not in theory !
I have done something similar in larger scales, juggling set track pieces to fit, even though on a drawn out plan or using “computer aided design” it does not seem possible.
I would be very interested to learn if this works.
