Yesterday, I boarded 83 at NYP to go to Baltimore with a 10 ride. Before departing, the conductor made an announcement that multi-rides and monthlies were not accepted on that train between NY and Philly. I went to find him and asked if it was accepted to go beyond Philly and he said "no, you must have a ticket for THIS train."
So I grabbed my things, got off the train, went back up to Club Acela and asked the rep at the desk who said, "no you were fine, it's just New York and Philadelphia and intermediate cities."
Of course, the train had already left. So, I am confused... which is it?
