they re on the same train line, the ex-Pennsylvania Railroad mainline (now the Northeast Corridor) between New York and Philadelphia, hench the Penn in both names. Until 2003, Newark was the next stop out of New York (a station in Secaucus NJ was added between the two to allow for transfers between commuter rail lines.)
Very easy. You can take any NYC-bound (eastbound) NJ Transit train from Newark Penn Station to Penn Station New York. The trip take about 15 to 20 minutes and fare is $4 each way, per person ($8 round trip, per person).Now, if that bit expensive, you can take the PATH train, which is a commuter interurban train, from Newark Penn Station to 33rd Street in Manhattan. The fare is $1.75 each way, per person ($3.50 round trip, per person).If you re taking the PATH train to 33rd Street, please change trains at Journal Square. The transfer between train is free.I hope this information is very helpful.Good luck and happy holidays.Native New Yorker
