That's quite alright, Phil. Most of the guys on this list are very up on the technical aspects of trolley operations. I am not. I have, however, learned to ask questions no matter how moronic they may be. I am glad I asked this question. 
  Fred III sent me an off-list e-mail once when I first signed up for this. In it he stated that everyone on this list puts their pants on one leg at a time. I took that to heart and became less ashamed to ask what I'm sure many percieved as "stupid questions". In fact, I once again thought of that before I asked this latest question. I thank Fred for taking the time to do that. 
  I have learned more than can be imagined just by reading the posts on this list and am very thankful to be here. 
  Oh, and welcome aboard Phil. You've already taught me something and I'm sure you'll teach me even more.

Pittsburgh was one of those companies.  Power / coast used in the description because it is more !descriptive! than toggle / coast isn't it.  Please accept my apologies for the confusion.

It was strictly prohibited on some properties to set the switch by power 
application because it causes burning to the overhead contactor and may 
cause also further damage to the track setting circuits. Pushing the track 
switch button limits the setting current to +/- 70 amperes while power 
application is always higher than 220 amperes.
