What do you mean John by "roller coaster ride"? Does the track curve a lot back and forth? Or are there elevation changes?
Two significant elevation changes over a distance of roughly a half mile in the area of the west yard lead junction. 35' drop, 20' climb followed by a 25' drop. The design in the preliminary engineering had most of the elevation change in west yard lead track YL2 as it flew over both mainline tracks and descended to the junction that was to be located in the 25' drop.
