NEW YORK - Commuters using some Metro-North trains may soon experience a shorter ride into New York City.

Metro-North just announced new train schedules that will cut two-to-four minutes off rides to Grand Central Station on most New Haven line trains.

Officials say that under the new schedules 74 percent of New Haven Line riders will experience a faster ride than with the current schedule, but 8 percent will experience a slower trip.

The changes are scheduled to go into effect on May 11. Metro-North plans to begin distributing timetables no later than May 5.

Also, Metro-North customers may soon be able to buy and display train tickets on their smartphones and tablets. The full MTA board is expected to vote tomorrow on a contract to develop new apps for riders to use.
