Whitehouse Station (Readington) is a fantastic place to live as you know! I grew up in WHS and have lived in Hunterdon over 40 years. Two of my children commuted to NYC for several years from Clinton Park & Ride, (non stop bus to NYC). My daughter also tried the train. She found the bus much more direct and faster, but it would be ridiculous for you to drive west to Clinton to go East to NYC. Hunterdon Transbridge has a pick-up in the Bridgewater area, which is on your direct route. You can Park & Ride there. I have a link on Favorites on my website for Hunterdon Transbridge and other commuter info! http://www.ceceliabogart.com. Please look at the schedule and if you have any questions, feel free contact me!
When I go to NYC - about two to four times a month - I drive to Newark, Park and take the path downtown, or NJ Transit to mid-town. Takes about about 45 minutes from my garage to parking in Newark and then another 30 minutes to NYC. Then its a question of whether its 5 or another 30 minutes when you exit the Path/NJ transit. So all in all about 1.5 hours door to door. Not bad for an occasional trip but definitely not something I would do every day.
Good luck and welcome to Whitehouse Station.
1. Search out the web for any express commuter busses in your area. These would be faster then trains if they're express.
2. Before going to White House station. Check out the possibility of parking at one of the train stations with more parking Raritan, Bridgewater etc. and going in to the city from there. (Lots more trains.) http://www.njtransit.com. Parking at NJ transit train stations usually involves some sort of permit or fee. Even ol' White House lot is probably at capacity during the day.
Raritan is pretty much the last stop on that line. Anything west of that will have few and far between trains from 8-9ish till 5AM.
Is there any chance of you picking someplace to live that is closer to your job?
