I just re-read an article from PTJ on Sunday that laid out how VIA was basically "on the brink" in 1984 and 1985. Transport Canada was investigating and trying to "figure it out" for VIA. Passenger ridership was heavily declining and the subsidy provided from the crow was heavily increasing, with not a lot of reliability in the system. They quoted how the equipment was heavily worn out, and even the new equipment of LRCs were not living up to expectations (experiencing a lot of failure at the time). VIA also was taking criticism for retiring its turbo trains, which were a LOT newer than the ex-CN equipment that the report hated. The VIA Board was even completely replaced in this time period cause the government (or Transport Canada) thought things were so bad. New equipment was seen as the answer.
Yet, even after having the Superliners tested on the Winnipeg-Edmonton route, nothing really dramatic with equipment came about till five years later in 1990 when VIA made the decision to CUT a lot of routes and refurbish its ex-CP stainless steel equipment, which the Transport Canada report of 1985 did favor overall. I hadn't realized how bad VIA had gotten in the mid-80s till I re-read this article the other day. And it quoted how successful Amtrak was against VIA's problems. Ironically post-1985 was sort of the beginning of the end for VIA's passenger rail footprint. The railroad tremendously re-trenched starting then, let alone the massacre that befell in the early 1990s.
I do think VIA will look into some sort of long distance replacement fleet (again), but it will be single level. I say "again" because a lot was banked on the Renaissance Fleet and that basically backfired....The Renaissance Fleet, I feel, are hitting early retirement. Its too bad they can't get more out of the Sleeper and Service Cars specifically. Overall, it was a large fleet of cars that were acquired, with only a portion put in service, and the remaining "shells" and "kits" sent to Thunder Bay for storage and final disposition a few years back I believe. Whether VIA goes in with Amtrak's order (if developed as it is supposed to be), they should, but time will tell, but it would make a bit of sense if they did.
