My wife and I are going to a play in NYC,how much would it cost take a train from Norwalk CT to NYC. What would it cost to take a Greyhound same distance

It will be same 8.50 train , the bus about the same plus the ride will be longer

The only option from NYC is the train, unless a bus is free, I don't know anybody who takes a bus. It depends what day of the week. If it's the weekend you will get off peak both ways and 22.50 will be right. If it's a weekday you will have to pay peak for 1 way and it will be a little more
