Having worked for PSE&G since before Transport separated from the E&G side I used to hear some interesting stories.
One of which had to do with the 1939 New York Worlds Fair and the use of Public Service buses to transport NJ people over to the fair. I was told that the All service vehicles were used so that they could run under the wires in NY, thus saving on fuel costs where they could. Sounds like energy theft in a way, doesn't it?
