The area needed to be expanded to 7' x 6' behind the wall - now there is an up and a down ramp - no need to change the main table for a reverse loop
The slopes are 3.9% and 3.6% for the outer loop.
It is hard to see the main level switch under the 7" height switches in the track plan - the straights are custom cut and 4 cut curves are needed.
Again, all GG wood tie track used.
