One more - here is an updated 1957 catalog layout with Fastrack. The outer route is now O-45 minimum, and grades are reduced to 4% maximum. The left hand side table is 2" higher than the right to ease the grades and for more scenic interest. The overall dimensions are 9X14. I replaced the curved elevated trestle over the yard with Atlas-O O-45 diameter which will look better as a trestle.
