The Fare Inspectors Return to the Newark Light Rail After a 4 Month Absence

I have quietly noticed that the fare inspectors had “disappeared” from the Newark Light Rail since June.  Today I left work at about 11:30 AM to attend a meeting in Manhattan.  I noticed on the outbound platform at Warren Street there were 5 fare inspectors doing their “high tech” duty of checking tickets and giving out summons to fare evaders.  One car had discharged passengers while I waited and every rider had paid the fare.

Why must NJ Transit keep this primitive method of collecting fares? Why do they need 5 while 2 are enough?  How much money is lost by paying these people?
