Here's a contrast of two VIA trains seen on April 26... April 26 2012 and April 26 2010 (both in Winnipeg).
In 2012, VIA 6431 led the Canadian out of Winnipeg.
In 2010, it was VIA 6420 leading the Canadian.
Notice a few differences. The obvious one is that the 2010 version had unrefurbished engines leading the train. Also, the 2010 version had three deadhead cars: Diner Empress and two coaches.
Tweedsmuir Park was on the tail end in 2012.
In 2010, Prince Albert Park brought up the markers.
A difference to note here. Excepting the deadhead cars in 2010, the trains were the same length, but the 2010 version had one less Skyline car in the consist. The 2010 train had another Manor car instead.
The two trains had only one car in common, VIA 8326, Franklin Manor.
Postscript: When I was photographing the 2012 version, I made a point of shooting the dome of Tweedsmuir Park. One of the passengers had a good look at me as they passed by.
Here's the video of the 2010/04/26 Canadian.
