As confirmed by New Haven/Northeastern Region General Order No. 312, effective Monday, September 21, 1970 all the trains presently operating between Grand Central Terminal and Boston with the exception of the Turbo Trains were moved from Grand Central Terminal to Penn Station that date. This is also confirmed by Passenger Service Notice no. A-4395. I have copies of all of the above in my collection to back this up. As for the Turbo Trains Northeastern Region General Order no. 409 effective Monday, February 1, 1971 moved the Turbo Trains from Grand Central Terminal to Penn Station and this made the transfer of all New York - Boston trains complete. I also have all public timetables through this entire period which all agree as to dates mentioned here. All of these changes took place before the start up of Amtrak later in 1971.
