These are the two options I'd like to see. Although I think it has been mentioned in the past that the streetcar would share track from Central Station to 200 S and 400 W, then have its own from that point eastward.
Orange represents shared track with Trax
This one bring access closer to Pioneer Park and could in essence extend Pierpont Ave an additional block to the west. This of course really would mean that the shelters would have to move.
