Why walk alone on the railroad tracks when there are streets parallel to the tracks?
RSBM It looks like there is a fence between the tracks and the bike path along the river. Maybe he was looking for a way onto that path, or preferred to walk it off quietly vs what looks like a busy/brightly lit sidewalk on Hall of Fame Ave. It is a strange choice, and a long walk. the first things that come to mind are he was heading to meet a ride down there, or he became despondent and chose the tracks for that reason.
