All well and good. I just find it hard to believe that a structure the size of a freeway overpass would not have a negative impact on home value. Most new homes are 3 stories tall and an elevated rail line would still tower over those to allow clearance for the underlying freight trains. I also don't see any certain sign that it would induce further development along the corridor considering the HSR would not even stop along the way. I have a love/hate relationship with the UPRR right of way, on one hand i think it allows for easy expansion of a usable metrorail route or bike trail and lends something to the urban nature of the area. On the other hand it creates a collecting place for trash, stops traffic far too often, and of course can be noisy. The bike path that they created through the heights on a old rail right of way would be pretty nice, but i still think a commuter line would net the best value add to the city and area. Perhaps below grade with street overpasses, pipe dreams....
