This link caused my confusion, where it talks specifically about the Hudson Bay train. But it is outlined in the Sleeper section as you noted also on this page that it is only offered between Oct 1-31. But they really make the Park Car section stick out for operating just one month out of the whole year.
I wish VIA would get some more exercise with its fleet of Park Cars. Perhaps even putting them on some of the trains heading up to the interior of Quebec from Montreal. I doubt the Chaleur will get a Park Car in place of its Skylie car, when they operate it as a separate train. Plus the Skyline car accomodates both sleeper and coach passengers. And it gets a good work out or patronage from what I've observed on some trips out to Gaspe. The Park Car no longer operates regularly on the Ocean (only during peak season). I think Easterly Class would sell well at peak periods, even without the full "Maritime Experience." I am sure they could just assign an extra attendant to the car - and dress him/her up as needed like they do for the Maritime Experience, but just offer appetizers and wine tastings and maybe some commentary etc. I would think around some holidays in what VIA considers the "off season" the Ocean become more populated.
Does anyone have a count as to how many Park Cars are required during peak and off-peak season for VIA's various trains? Do they ever operate the Park Car on the trains that go into the interior of Quebec? I suspect the reason why VIA is willing to "rent" these cars out is because they have a little bit of a surplus. But I would think operating such on the Hudson Bay train year-round wouldn't put a huge dent in the fleet's availability. Just two train sets are required for the tri-weekly Hudson Bay trains right? Perhaps they could rent them to Amtrak for operation on the Adirondack between Albany and Montreal! A Skyline Car would work better though. Although for the Adirdonack operating with a Park Car (wishful thinking) I'd be willing to occupy a sleeper for my own "space." I am sure the border patrol would have an issue with it, as well as VIA and Amtrak though!
