Ok, just making sure you're aware. Passenger rail in Canada has priority lower than zero, the truth is the railroads would very much prefer to abandon it completely in favour of 100% freight operations, but there are political pitfalls.
That said, I've had lots of fun on The Canadian. Many tourists from all over the world ride that train, and unlike most Canadians, they know how it's done. They come fully stocked with food & drink, and they bring the correct attitude. Meeting them is a blast, much laughter and good times.
I'm sure you'll be fine, hope you enjoy your trip and get some good flying in! Pilot DAR knows what he's talking about, good advice there.
