I been listening to the local tower. The tower person sounds like he is keying the mike from across the room. Hard to understand, boring listening.

Has anybody else ever heard this on here?

I know that Amtrak in Philly from Zoo interlocking to Grundy is controlled by a remote dispatcher who controls all of the signals and switches. Other than Zoo Tower all the towers are closed. That's interesting on the Harrisburg line that Thorn Tower is still open and that there isn't a central dispatcher who controls that interlocking.

Yeah I only worked on the railroad for five years because I didn't want to go into Railroad Retirement. I was an engineer with SEPTA, then became a tower operator and then went into rail operations at the regional rail Operation Center when it was in Suburban Station. Moved up the line fast because I had a graduate degree in another area. Worked there from 1985 to 1990. SEPTA trains only went to Paoli at that time then every other train would go to Thorndale.

In those days every single Tower was manned with operators who operated the switches in the interlockings and managed the small yards.

And those days we also had temporary block stations at night for track work. It was a good assignment because you only had maybe one Freight at 4 a.m. so you could just put your red board out with your Red Lantern and go to sleep. We used rail phones with a loud ring so if something extra came along it would wake you up. Set your alarm for the freight, give them their train orders, throw the manual switch and cross them over LOL that was the old Book of Rules of course, now it would be a form d. Also crossovers are all remotely electronically-controlled.

Overbrook also, wow. I've been in Zoo Tower, back when I was running... Zoo was the largest interlocking in the world but I think there's a few bigger now somewhere in the world. Very difficult to qualify on zoo as an engineer, numerous front-end rides and 2 book of rules guys in the oral qualification exam. Long time since I've thought about this stuff. :)

From what I've read lately it sounds like Zoo has been considerably reduced in size and complexity, in preparation for control being moved to the central dispatch center.

Oh I can think of a dozen places where it could be cutback. We can't lose sight of the fact that at one time there were many many more trains running many more places than there is today. Also it's not cost effective to maintain decrepit, crumbling mini tunnels and track that is just not needed.
