That was a long Norfolk Southern double stack train that you caught at Ash Street crossing. You moved to Bridgeport Junction where railroad tracks and the Chicago Transit Authority's Orange Line to Midway Airport meet along the Stevenson Expressway (I-55) in the Bridgeport neighborhood of Chicago, Illinois. There you caught three CTA Orange Line trains and an inbound Amtrak train. Thank you, Frank, for this short video from 25 May 2024! (Posted 3 August 2024 at 2024 CDT.)
