[PRCo] Re: Stumped

[Herb Brannon]

>From the Signal Manual (1973 PATransit edition -- same as PRCo except for signal drawings rather than photos) :
   
  "At each end of the single track three contactors are installed on the trolley wire for the actuation of the signals as follows:
   
  (a) Two contactors are mounted on the trolley wire over the track by which cars enter the single track block. The first of theses contactors engaged as the car approaches single track is known as the Preliminary Contactor, and the second one, which is mounted about a car length beyond the first, is known as the Counting-In Contactor.
   
  (b) One contactor is mounted on the trolley wire over the track by which cars leave the single track block and it is known as the Counting-Out Contactor."

  Looking at the photo again.......

Very Short Siding??? Note the two contactors for the Nachods -- 
presumably the one closest to us clears the single track behind~?~!~? 
Then we should see a contactor on the 1707 overhead heading into the 
single track but only the one to clear the single section behind is seen 
in the distance. Doesn't seem right -- contactor further back 
appears Waaayyy to close to the single track and TrolleyCar would be 
well on top of the points or front end at least beyond the track frog 
before activating.
