I've always wanted to try to hand lay a curved double x-over. Just for the challenge. I started sketching one out a while back, but shelved the idea as I had a whole layout to work on.
If memory serves, there was a layout profiled in MRR'er mag with a hand laid double cross over. The article mentions it in a photo tag line, however does not go into details as to how it was built. So a single curved diamond can be done, with careful planning....hmmm... but where would I use it???
Life should not be a journey to the grave with intention of arriving safely in a pretty and well-preserved body but rather to skid in broadside in a cloud of smoke thoroughly used up totally worn out and loudly proclaiming
WOW! What a ride! H.S.Thompson
