Transport Canada has made more than clear that the LRC cars won’t have any kind of second life after its Corridor deployment - neither at VIA nor any tourist railway. They already have to get retired progressively as we speak and independently of the question whether the delivery of the new trainsets can keep up…I could certainly see LRC coaches that are displaced by the new sets showing up in northern Quebec service (where no sleepers are involved), but longer distance remains a mystery.
There is only one maintenance facility on this planet with experience maintaining and repairing Renaissance cars and that is in Montreal. Given the poor reliability of the Renaissance cars, they are not suitable to be sent across the country for multiple days…I saw a YouTube video of someone riding the Ocean (Halifax-Montreal) earlier this week, and it looked like its consist included both newer sleeper cars (where the content creator's room was; he described them as "Eurostar hand-me-downs", but they looked pretty nice) and the older Chateau sleeper cars. How long would it take to put the newer sleeper cars on the Canadian, and how would that alter the trip experience for passengers?
