If you are looking for an economical and interesting way of travelling between two points between Jasper and Prince Rupert, then economy class on the Skeena is the way to do it. If, however you are looking for a memorable experience and the budget will stand it, then despite some of the previous comments, opt for Totem class.
Why? Firstly the views. The entire journey is through stunning scenery. The wrap around windows of the main car mean you can sit back in your very comfortable seat and in any direction you look your eyes find a fabulous view, not somebody else's luggage or the framework of the train. Secondly, your ticket entitles you to the use of the observation car. As well as being a piece of living history, being built in 1953 and immaculately preserved, it gives a totally different view from the top of the train. On our journey the economy class was very full wheras Totem much less so. This gave us the freeedom to get up and move around. If you do the complete route you are on the train for the best part of twenty hours over the two days, not including any delays from freight trains,and this ability to stretch your legs, if only to climb the stairs to the observation dome is very welcome. The meals are included in the price and although they are only airline style, the quality was better than you would get on most aircraft and coffee, water and simple snacks were available on demand.
We felt particularly lucky on our trip with the train crew. Tracy, the service manager, has a passion for her job that shines through every minute of the journey. She was able to answer all the questions we had. If she was busy elsewhere on the train there was a small library of books she had provided for our use, including a very comprehensive one she had written herself that went into great details of the route and its history. Her assistant on the route, Stephen, is a rookie this year and whilst he did not have Tracy's encyclopedic knowledge of the route, he would always try to find an answer. He also had a fund of jokes, some of which were even funny! From what we heard, the other crews on the line are just as good.
