Theres also going to be a bridge at 42nd street as well as at 45th street over the tracks |
You catch an interesting point here. 45th Street actually sits on a bit of a rise. If the tracks were to come to grade before reaching 45th, as the original plans called for, the trains would end up having to first come up more steeply and then travel down a slope as they headed west, immediately prior to starting to climb again to get over Sarcee Tr. I would not be suprised if the design/ build teams were pushing for the trenching change as it helps simplify the engineering of the grade (which trains are very sensitive to).
