You could file these pics in Current New York if there was such a topic. I took them this morning around the old MO tower in the Bronx behind the 139th St Post Office next to C.Hayes H.S. Exploring with my 4 year old helper.
She was bored so I'll have to go back to get some better shots. There is a nice ConRail painted 40ft double door boxcar in there.
A few weeks ago on another Bronx walk a got a few more. First up is a MetroNorth MOW Geep under Macombs Dam Bridge.
This is from the NYC bridge over the site of the old Put. Now part of the bridge is open and part is a ruin that leads to the new MetroNorth car barn.
