I love switch back, point to point RRs. I'm just starting my 2nd standard gauge, non logging, non mining RR. More like Hagans switch back on the L&N. A raised main line with a SB/tail-track halfway down, then into industries at ground zero ...I find with small available space a SB gives the 'crew' welcomed work to accomplish per trick (shift, session)..You've done a great job here.. Hope you're still up and running....M
