After sitting outside at ExpoRail, the Canadian Rail Museum in Saint-Constant, Quebec......”Sibley Park” has been moved into the Angus Pavilion where it will be restored. Sibley was considered surplus by VIA Rail and not rebuilt as part of the HEP I program back in the late ‘80s.
Yes -- that's actually why they're called "Park Cars", IIRC. They had some formal official name like "observation end car" or something but they all had "____ Park" names so...
I work with one of two park cars in the USA on a regular basis and the only one that still operates. It still lacks HEP. But the owner did recently restore it to Canadian Pacific livery.
