I've been doing some research on N&W's engineering standards and have a couple of questions. According to N&W standard plan L-334, in a cut, the roadbed is 12 ft wide from centerline of track to the edge of the ditch, and in a fill, the roadbed is 16 ft wide from centerline of track to the top of the fill slope. Did N&W have a standard or typical method of transitioning the width of the roadbed from 12 ft in a cut section to 16 ft in a fill section? If so, how did N&W make the transition?
Also, the sides of the ditch in the cut section are sloped 3 to 1 and the sides of the fill embankment are sloped 1.5 to 1. How was the ditch in the cut section transitioned to the slope of the fill section?
