I was born and raised in New York, so I don’t think much about getting around. The subway is second nature to me, as are trains like Metro North and NJ Transit. I figured there’s plenty of people who may not know how to navigate public transportation. You can save a bunch of money taking the train to Newark Airport. Here’s how to get from Manhattan in New York City to Newark Airport via train, originating at Penn Station, buying a ticket and connecting to AirTrain.
