Heavy rail tracks already exist on the IBX, do they not? Now you have to pay more to remove said tracks, or to build new infrastructure around it. So then what happens when there's more traffic on said roads, because of light rail taking up space? Explain the capacity light rails have, compared to a commuter train? Again, this isn't one city, this is two boroughs with a lot of people. Will light rail get them where they need to go in a timely manner? I was hoping we would get a subway line as well in the future, but I don't know if they would ever do that.
