As I always comment on threads like these, one of the supposed benefits that make hyperloop cheaper than rail is lack of expansion joints. The tube floats axially except halfway between each station where it is fixed. There's only one sensible in between station (Red Deer), putting each section of tube at 75km. If steel and assuming -40C to +60C temperature range (taking a guess at the tube's temperature on a hot day), you need +/- 27m for thermal expansion at each station. This needs to somehow maintain a vacuum seal and is also where you are boarding people, presumably through airlocks. Sure, there could be solutions but I don't find it credible that the feasibility is higher than a train.
