Another fine update Doc. Looks like a slight adjustment is in order to line up with the distant trestle.
Thanks Dave. You are observant about the line across the Little River valley and watershed. The track the surveying team is working on is descending at a 1.5% grade, while the trestle across the valley is ascending gently at a 1.5% grade. If I did my math correctly the “upper” line will cross over the “lower line” with 12"-13" in clearance. The classic “folded dog bone” crossover. Reusing geometry lessons from years ago has really been interesting and entertaining. Here is the track plan I am following from Garden Railroad magazine. The angle of the picture across the valley is the same as “GR’s camera 3” on the track plan. Doc Tom
