Wow, found a photo of this same tower from 1967: http://www.rr-fallenflags.org/bo/bo-coal-tower.jpg The clearing in the background is where I-80 is now. This area was also an interlocking with the LE&E. 3 left tracks under the tower are PRR, right 2 are LE&E. http://www.rr-fallenflags.org/prr/prr-int-p14.gif
