I kinda get it but by interlockings you mean major switch points right? And tower means dispatch control tower right?

 

An interlocking is the whole switch plant controlled by an interlocking machine. Towers are where the interlocking machines are located and a dispatcher works in the tower, controlling the movement of the trains and making sure they are on time.

Back in the day, many interlocking zones were manned vs train crew throw switch (some manned 24 hours a day) in a building (tower). Inside the tower were levers, the levers would be controlled by a person who moved them in accordance to wherever a train needed to go. Slowly over time, more important towers were put in control of smaller ones, or ones close by. Today the equipment found in towers can vary from the most up to date electronics, to totally empty and abandoned with nothing in them replaced by a metal box nearby.

 

There is actually a tower which straddles the tunnel portals in NJ, which used to be guarded by military personnel do to its strategic and vital importance. If you ever get to catch an open cab door you can still see the windows. Other towers like JAY were built with toilets kitchens etc so the crew didnt have to leave. One of the biggest PRR built towers i know of, is ZOO, it's basically a mega-sized version of JAY, because it lay where the northeast corridor and keystone/broad way line to chicago met, the busiest interlocking in the PRR system for many years. I'm bringing up PRR, because for many years they owned LIRR, and much of what is left of the wayside buildings & structures were built by PRR and simply handed over to (MTA). (MTA) kept some of the structures, i'm not sure how many are left functional, but at one time they with the engineer got trains where they were going.
