Dave Pogue wrote an article a few days ago about an app that has been on my wishlist for ages: All Aboard an App for Suburban New York Commuters
The MTA did open up its schedule information to developers for free so expect new apps to come but this is a great (free) start.
onTime : MNR FREE (Metro North Rail Ad supported) by Mobileware Inc.
Find the next Metro North Rail (MNR) train schedule in a New York Minute. onTime is fast and easy to use. It is designed with commuters in mind. With onTime : MNR, you can look up the MNR schedule anytime anywhere without having to carry and dig through paper schedules. No more carrying copies of paper schedule and trying to figure out the next train. Be onTime and be environmental friendly at the same time.
It’s good, but want BEST?
I owned this, as much trouble as the paper version.
I now use Brayne Trainz: Metro-North. Much easier.
