DOCK Tower Closes (1937-2017)
Well it looks like the Duke Nukem Forever of re-signaling projects has finally run its course. While The venerable DOCK tower may have been celebrating its 80's birthday this year, the project to replace it was well into it's second decade. DOCK was built along with the equally magnificent Newark Penn Station and sat just to the east where it could oversee the operation of three movable bridges over the Passiac River. An impressive structure it sat three levels about the track with the ground floor housing control equipment for the bridges' power supply.
The last of the main line NEC towers, DOCK had previously run as a trio with UNION to the west and HUDSON to the east all the way into the early 21st century. . . .
