I know many people who wish they could, as pedestrians, cross the railroad tracks when a train is going by. I'm envisioning that this could be done in two locations, both about half a block west of Broadway, one for each set of tracks that goes through downtown.

They could be done gradually, one at a time, and then they could be made longer and longer until they met, and then they could gradually have roofs added, and then making them enclosed, and then climate controlled, and then they would be part of an expanded skywalk that would connect with the rest of the skywalk through the second story back of the Black Building.
