I think it's nearly impossible to comply with the five-minute rule. For the switching operations, there is room for improvement on that. Train design can be looked at with respect to where the traffic that needs to be switched is in regard to the location on the train. If it's on the back end of the train, you're going to be on crossings. If it's at the head end of the train you won't be following crossings. For the situation in Regina I proposed a fix to blocking the Ring Road and those 11 crossings by making sure the rail was lined up for that movement to continue moving until it had cleared, without having to be stopped and go at low speeds and block those crossings for extended periods of time.
Shorter trains, realistically, are just not going to be an option for the carriers. That's just where we are today, but as for preventing them from stopping in key locations like highly populated or at-risk areas, I think there's definitely room for improvement on that.
