In anticipation of increased holiday travel Amtrak has announced extra trains and more seats will be available countrywide, including the Northeast Corridor. Passengers in the Northeast Corridor should be aware that "Holiday Extra" trains, which operate on Sun., Nov. 30, use borrowed commuter train equipment and may have fewer amenities than regular Amtrak service. Many regularly unreserved trains will require reservations during the holiday travel period, including Keystone Service in Pennsylvania, and Empire Service in New York. The Thanksgiving holiday is the busiest travel week of the year. Last year, Amtrak carried more than 750,000 passengers during the Thanksgiving holiday travel period. Higher passenger counts are anticipated this year. Information is available at amtrak.com.
