The intent to use the Union Branch at one time involved a new line extending from the Forest Ave. crossing alongside I-295 to a new station near the current site of the Miss Portland diner, and then on to a new bridge across the mouth of Back Cove joining the GT in East Deering. A major part of the goal was to increase visibility of the service, but given the ridership in the ensuing decades I don't think that's truly necessary now. Plus, the proposed station location didn't anticipate the commuter usage of the service, so it probably didn't have enough parking for the current usage pattern.
