There is a proposal for a Montreal—New York City high-speed train . On October 6, 2005, the Albany Times-Union reported that New York Governor George Pataki and Quebec Premier Jean Charest "called for the creation of high-speed rail service between Montreal and New York City as a way to boost the regional economy during the third Quebec-New York Economic Summit [on October 4]". Little progress seems to have been made since then, and the Federal Railroad Administration has instead preferred a link between Montreal and Boston, despite the fact that independent ridership analyses have suggested that the New York state route would be much more promising. 
Amtrak ordered another seven Turboliner trainsets, which were delivered between 1976 and 1977. These were manufactured by Rohr Industries , and were known as RTL Turboliners.  They were based on the earlier RTG series, but had American-style Janney couplers throughout  and a different design of power car cab .  The standard configuration of each set was five cars: power cars at either end, a food service car, and two coaches.  In that configuration, each trainset could carry 264 passengers.  At times, Amtrak operated Turboliners with an additional coach cut into the consist.  These were the final gas turbine trainsets purchased by Amtrak; conventional diesel locomotive-hauled trains proved cheaper to operate.
