LC: There is still a pony motor of sorts used today in the far north where temperatures go in excess of -40F. It is an air starter usually supplied by the vehicles air brake system. At night or extended down time periods when air supply could leak off, they line them up at a central air supply. I saw a bunch of these sold at a public auction in Halifax NS about 10 years ago. Mainly big tandem trucks and construction equipment being sold as parts vehicles. Some of them were conventional highway tractors. The day of the auction they had a tire guy going around with his mobil truck jump starting these. I know a couple of guys bought these for dump trucks here in what we call the south in Canada. Most soon got changed to electric starters. The air starters were almost as much trouble as old describes early pup starts. I know a guy that ran one of these for years in a dump truck. He claimed it was less expensive as one had the air supply anyway for brakes, and the truck didn't require anymore battery than his gas pickup. I didn't know him that well, but his friends called him stonehead. I think they considered him rather stubborn on issues like air starter among other things.
