can i get a ticket at the station for an one-way trip to New York?

For metro north line, I highly recommend downloading the app. Buy your ticket online, see train schedule, prices, easy to read and use

Yeah! Why would you think otherwise?🤔

Yes. Amtrak and Metro-North. Metro-North has many more departures and I believe a one way fare is $16.

It will be expensive though if you're going to take Amtrak. It's best to buy a ticket ahead of time online.

Yes

Absolutely.
