The original 1955 Budd CPR Canadian consist was baggage-dorm, coach, Skyline, diner, Manor car, Chateau, Park car. Would you believe near-original consists were running on CN's Kingston Sub in 1983? Except for the ex-CN F's, and sometimes missing the diner, shortened winter-spring consists of VIA train 1/55 were nearly-original. In summer, up to three Budd sleepers were in the train, in winter sometimes just one. And Budd diners were also in evidence.
This is the kind of uniqueness that we're lacking today. But wait, looking forward to the 1990's, there were still some pretty cool consists being operated by VIA, blue & yellow and stainless steel, F40's and LRC's. That's seven years beyond 1983, where I'm currently data-mining. Highball.
