If you remember the old Bell System, you might not know that all those monopoly profits went into building a long distance network that was literally bomb proof, Atomic Bomb proof. Across the country there exists to this day a network of bunkers to keep the phones working in case of nuclear attack. They were linked by a series of microwave relays and L4 co-axial carriers. So next time when you're shouting "Can you hear my now" into your Cell Phone, think of what "6 9's of service" used to mean.
The other cold warriors in South Jersey are the SJRR's fleet of Alcos. Granted most of them are Canadian imports, but it's close enough. You don't see any imported diesels from Lada or Gaz.

And a brief tour...
MILLHAM tower in Hamilton NJ is located on a straight stretch of NEC that used to contain a complete 4-track interlocking. Ultimate the interlocking was removed during one of the NECIP's as Trenton area freight traffic declined, but was partly compensated for by the construction of the new Amtrak HAM interlocking about a mile to the east. MILLHAM was controlled by what became the prototype "corridor" style tower built in 1941 which replaced many older plants. The peaked roof is a new addition to shield the leaking flat roof.
The bunker at Cedarbrook. The pryamyds are vents and the brown thing on the concrete post is a gamma ray detector to alert the ppl inside to a nuclear blast. It's amazing the quality of service we got when AT&T was still a monopoly. Even after a nuclear war the old network would have still functioned.
Old microwave relay horn antennas. If you hook your laptop up to one of these you can get 802.11b wireless up to 30 miles distant.
Wow...that's a lot of backup power. Something still uses this place.
