That is very true. Today I sent you by e-mail an article from the Environmental Protection Agency in the U.S. They did a study on the Chicago rail yard. They were able to reduce their idling times by 80% simply through the use of new technology, and the payback period on it was two and a half years for the cost.
There certainly are technologies out there that can be utilized by the rail lines, yet they're archaic organizations that don't see a need to change, so part of it must be legislated; then ongoing supervision by the Canadian transportation association would allow them to deal with specific situations that arise from time to time outside the legislation.
