The NJ Transit ticket was $12.50 from Newark to Trenton. When we arrived in Trenton we located the machines to purchase the SEPTA train ticket. The ticket was $9.25. The SEPTA Train took us from Trenton to Philadelphia a few blocks from our hotel. It is little confusing for newbies, but I imagine once you get used to the system it’s pretty easy. We could have taken the Amtrak, which would have been over twice as much and probably an hour or so faster, but we decided to try this option instead since I hadn’t seen my cousin in awhile and it would give us plenty of time to catch up.
