We see that the body was found at "Grand Avenue" at around 4 A.M. after looking up Grand Avenue on Google, I discovered it's a railroad. When Jack, in his flash back (or flash forward), pulls onto the bridge and stops his car, you can distinctly hear a train. While he is stepping onto the ledge, it's hard to tell what's below the bridge, other than the cement part he is over... but I'm willing to bet it's a train track.Any thoughts?
