I have to take my daughter and her friend to a NJ Transit train station this afternoon. If I'm traveling north on Route 1, where do I get off for Hamilton and is it easy to find once off the highway? I've taken NJ Transit from Trenton and Princeton Junction but never Hamilton. Are there ticket machines or a real person there?

I hope this isn't too late for you - but I believe the road going north from route 1 is Whithead Road. Go to the bottom of the ramp - turn right. At the immediate next light turn left and it's up on the left about 2 miles or so. You will go over the tracks and need to turn right - follow the signs for parking for Hamilton since there is no left turn into Hamilton train station from there.
There are numerous kiosks for ticket purchase and a ticket window. Very easy to find. Hope this helps!

Thanks Fairway. I am leaving soon and I bet I will hit a lot of traffic on a Friday afternoon!

One more question: I am just dropping these girls off. If I follow the signs for parking will I get close to the spot where you buy tickets?

you really want to get as close as you can to the station building...that is where you buy the tickets.
