Reply to "4x6 027 Track plans...Ideas?"

Here is my 74" x 38" O-27 layout:

It required several custom-cut sections. Unlike in the track plan pictured, there is play of room for the longer spur. What I like about it is that you have reversing loops for both directions and the variety of running on both an inner and an outer loop. But you would be able to add a 10" straight on the right and left side, to increase to a 74" x 48" layout.
