I was made aware by an “in the know” person that when a platform pile up like this happens, merely walk to the stop one block away and board early. You will be nice and comfy by the time the train rolls around to the River Market North stop.
Also, scuttlebutt is that for next year’s Riverfest, as many trains as possible will be lined up awaiting to start the southbound jaunt at the conclusion of the fireworks show.
