Fred's HOGRR suggestion is good. If the importance for you is portability to get the 4x8 away from the way to operate, you can stack the HOGRR sections and take up only one foot of the room when not operating. Like the Clinchfield, you will need to duck under if operating from the middle, but you can also operate from the perimeter. I seem to recall that there are some N-scale versions with better sidings and more spurs. There is a Yahoo group site for HOGRR also (limited activity though): HOGRR : Heart of Georgia Railroad Layout The N scale thread: Yahoo! Groups Good luck!
