I was under the impression that the Sept 29th northbound trip was a positioning trip for the start of service on Sept 30 and not a revenue trip. Happy to have been mistaken.
Amtrak 60 and 61 were listed in CN/CV and B&M employee timetables as 733-27 and 26-732 respectively up to at least 1987. An eastbound to Amtrak, 60 was Northbound (Outbound) on B&M and Westbound on CV/CN, hence the odd numbers. CN posted the train numbers as 27 and 26 at Central Station in Montreal to avoid confusion with Montreal-Toronto Rapidos 60 and 61.
Pine Tree State, an ex-PC/NYNH&H 6 DBR Lounge, was a nice touch. Along with Nutmeg State, it was built for the CN/CV/B&M/NYH&H/PRR Montrealer/Washingtonian by Pullman-Standard in 1955. Two similar cars (Keystone State and Bay State) were built at the same time for the Federal. The buffet-lounges were set up to supply light meal and beverage service for 12-15 passengers to eliminate the need for a dining car. Now privately-owned Pullman Dover Harbor and sister Dover-series cars were used on the Montrealer/Washingtonian until the State cars were delivered.
Since I found the book with the info, the rest of the consist is worth a look.
4036 and 4038 were both ex-NYC, 4316 (nee PRR 5716A) was the first unit to get an Amtrak arrow (on a black body). 4036 and 4038 were later Amtrak 256 and 257, 4316 was later Amtrak 322 and 461.
70 seat Coaches 7000, 7002 and 7003 were ex-RF&P, all built for the Old Dominion in 1947 (ACF)
Coach 3952 was an ex-PC snack bar coach rebuilt by PC in 1969 from a 64-seat coach built for NYC in 1946 (P-S)
56-seat coach 5611 ex-SCL/SAL, built for the Silver Meteor in 1939 (Budd)
56-seat coach 5613 ex-SCL/SAL, built for the FEC Henry M. Flagler in 1939 (Budd)
Diner-Lounges 8300 and 8301 ex-C&O, built for the Chessie 1948 (Budd)
10 Rmt 6 DBR Pacific series cars ex-UP (50 cars, Amtrak got 43) built 1950 (Budd)
6 DBR Buffet Lounge Pine Tree State ex-PC/NYNH&H for the Montrealer/Washingtonian 1955 (P-S)
Amtrak's Montrealer was my "home" train until it was dropped in 1995, the Vermonter serves that role today.
I'll try to post a new question tomorrow.
