I would like to know what’s the name of the passenger trains which theses trains if there was severals between Montreal to Boston round trip under the Central Vermont Railway,Canadian Pacific Railway and other railroads companies if there had trains between these cities before Amtrak and under the control of Amtrak ?
Look for old Official Guides and timetables for the B&M,CV, CP, and MC. See swap meets, train shows, classifides in Trains or through NRHS and R&LHS chapters, even local hobby shops. There are some great books, too, in your library.
These names were in use by 1930, but in 1916 the B&M did not name its trains even though it offered the through service. From the Guides that I have, I would say that these were the only names given the Boston-Montréal trains.
After the B&M dropped through service between the two cities (by 1962), there has been no through service.
