I'm originally from Winnipeg. I did some work on hydraulics and pneumatics in the western yards, in the Symington Yard, and I worked in the Transcona yards. There are ways of getting compressed air through brake lines when it gets cold, but there are constraints on contraction between tracks and wheels and equipment.
Could you speak to what might have been done in terms of putting intermediate compressors within the car system, things that you might have tried in order to solve the technical part of cold temperature operation?
