There is plenty to do in White Plains, so if you are coming from NYC and don't have a car, Metro North is the best and easiest way to get here.
There are trains leaving Grand Central every 10-15 minutes (even on weekends) and if you time it just right you just may get on an express train that takes all of 31 minutes from Grand Central to White Plains making only one stop at 125th Street before moving on to White Plains.
Check out their website for fares and discounts.
White Plains is one of those lucky towns that have a bit of everything for public transportation in this country. The Metro North station at White Plains has office towers right next door as well as the main bus terminal.
The run to or from Grand Central Terminal in New York to the White Plains station varies anywhere from 33 minutes to 52 minutes depending on the particular train you take. Current fares are $8.75 each way during peak times and $6.50 each way during off peak. As always, higher fares apply for tickets purchased on board the train from conductors (currently $14.00 each way peak, $12 off peak) so be sure to buy your tickets at the station before hand.
The trains are almost all the new M7 style EMUs with high seats for all in a 2 and 3 set up. Quieter than older trains and now with electronic signs and announcements that you can actually understand, the upgrade a couple of years ago was well received.
Please be aware that because these are commuter rail cars half the seats are always facing the “wrong” direction. If this is an issue be sure to walk to the other half of the car closer to the direction of travel to find seats facing forward.
