Need advice for wheelchair travel in Banff, Canada?

We want to go to Banff, Jasper etc. We want to know if anybody has taken the "Rocky mountanier" train in a wheelchair and how trully accessible was it. Any other information on accessibilty in the parks would be appreciated. Contact names would also help. Thanks

Call the train service and ask if it's wheelchair accessible, before heading there, and also ask if any park they know of is wheelchair accessible. I have never been there, so I wouldn't know what else to tell you.
