In my brief, I mentioned that the Canadian Council for Rail Heritage was looking at a draft evaluation mechanism for historic railway equipment, and this is based on what a lot of conservators and architectural historians are doing for buildings. They've adapted this. It's being done by Jim Cullen, a former senior management person with the California State Railroad Museum, and Hal Kalman of Commonwealth Historic Resource, and they do go into a number of questions that they ask, in many ways.
I will leave this in our package for you.
