I'm also interested in the history along this route, I can find a lot of info about the Grand Trunk Pacific but very little about the train itself, which year it was streamlined, historic consists, schedules, etc.. All I can find is that it used to be Trains 9/10.
Here’s a little history:
Trains were generally a through Jasper-Prince Rupert service (first timetable below is from Oct 1960.
I did find a timetable from Oct. 1964 when Jasper-Prince George was and overnight train connecting to a daytime RDC Railiner between Prince George & Prince Rupert.
Here’s one from Oct 1975
.....and Summer 1980 along with a sample consist from that era:
VIA#10 at Jasper
CN 9176 FP9
15407 Steam Generator Unit
9482 Baggage Dorm
5548 Coach
1342 Diner
Green Hill 6-6-4 Sleeper
In November 1981, the Super Continental was discontinued, eliminating passenger service between Winnipeg and Vancouver on the route VIA’s Canadian uses today. VIA then extended the Skeena to Edmonton from Jasper.
On June 3, 1984 the “Panorama” was introduced between Winnipeg and Edmonton. Returning passenger service to the CN line via Melville and Saskatoon. It also replaced the Skeena between Edmonton and Prince Rupert......Basically a through Winnipeg to Prince Rupert train (tri-weekly west of Edmonton)
Around this time, fall/winter 1984-85, VIA leased an Amtrak Superliner consist to evaluate and used them on the Panorama between Winnipeg and Edmonton. I’ve never seen anything to indicate the Superliners ran through to Prince Rupert so a change of cars was required in Edmonton.
VIA #3 Panorama, arriving Edmonton on Sept. 28/84
Amtrak 319 F40
Amtrak 31041 Superliner Coach-Baggage
Amtrak 34030 Superliner Coach
Amtrak 38025 Superliner Diner
Amtrak 32019 Superliner Sleeper
VIA 15301 HEP Generator Car
On June 1, 1985 the Super Continental was re-launched. Replacing the Panorama between Winnipeg and Jasper and extended through to Vancouver. Returning passenger service to the CN line between Red Pass Jct. (Jasper) and Vancouver for the first time since Nov. 1981. The Skeena name returned as a through Edmonton to Prince Rupert train which was attached to the Super Continental between Edmonton and Jasper tri-weekly. (Engine+Cars+Engine+Cars) This was the way the trains were operating at the time of the Hinton disaster in Feb 1986.

In the mid 1990s, VIA split the train into the separate daylight runs it still operates as today.
