If you'd asked me that question two years ago, I'd have said no. About that time, Canadian Pacific announced a $2 billion investment, mostly on western corridors. Canadian National waited about a year and a half and only announced a similar investment, practically a photocopy of the CP program, after considerable embarrassment: criminal charges at McBride for the trestle incident; long trains that people told them not to run on the B.C. Railway, which had recently been purchased by CN; spills in the canyon at Squamish; and a number of other incidents that are pointing the way to too much train on too little track, if I can put it that way.
On October 31st, 2006. See this statement in context.
