CN uses rail-mounted jet-engined blowers to move snow both in yards and on the main line in the Halifax area. The noise is almost deafening and there is a very very strong smell of kerosene. Most unpleasant. This video shows an ESSCO jet snow blower in use at three separate locations over the last 10 years.
The alternative is manual snow clearance - see https://youtu.be/Zek_bSR3Bvc
