Hi Tom,
Spectrocell - it back up to the line at the corner. Remember that little hill and the tracks are at the top.
By the way, Tank Car Corporation (what reconditioned tank cars) closed about 5 years ago - it's a high rise condo/apartments now. Miller's Trash is gone too.
By chance, did you see the Santa Train somewhere between 57 and 59? Had a T-1, Flat Car with Santa and his elves throwing candy to the kids, a passenger car and red caboose. I was standing right next to the drivers - can't forget the sight, sound and smells of that engine. Or when it pulled out and shot down the line like a rocket.

If you mean where the Pennsylvania Trenton Cutoff crossed Bethlehem Pike, It's now called McGurks. Was a couple of other names before.
