I'd 2 circles of original blue railway track, lost 1 inner, bought mixed batch of track off eBay, as more inner than outer bought more track & to get discount 12 outer & 4 inner to bring N° of outer & inner = at 1 pair short of 4 circles. So I set myself the challenge of using all in 1 layout with no dead ends. I'm emptying old caravan so room there. 63 curved, 14 straight pairs, 2 crossing & 2 points.
My question, is there a maths equation or computer program to say if track layout meets up? Instead of trial-&-error method. R10L4XS2R8S1PR1XS2R12PXR1L2XR7S3R4S1R1S1P were R=right, L=left, S=straight, X=crossing & P=points.
Noticed in Ideas book, 3/4 circle, then 2 other way then 1 straight, Then other end 1 same way, then 3 other to become touch & parallel to other to go to points.
