Thank you, Mr. Chair.
I want to follow up a little further on the path Mr. Albrecht was going down at the beginning. There's a very interesting graph on page 7 of the Library of Parliament's briefing document we received, and I'm just wondering if you can help me understand the attribution.
In 2005 there were about 31 or 32 main track derailments and seven accidents with dangerous goods releases. In 2012 we were down to about six main track derailments and about two to three accidents with dangerous goods releases. So we had fewer main track derailments than we had accidents with release of dangerous goods back in 2005.
I'm just wondering if there's anything that any of the officials would attribute that change to. What would you look at to say why we had this? It's obviously a good trend, but what would you attribute that to?
