I saw a train of these in Quebec and then an identical train in Montreal, doing on an airport what tugs and icebreakers do on the nearby rivers.

Any ideas on the manufacturer?  I guessed Bombardier . . .

This photo I took last summer in upstate NY near the snowiest town in the state, but this is for clearing roads and streets, not airports.

The one above is an Oshkosh, so how about this one?

Here’s the answer.  I’d have guessed Oshkosh, which started up in 1917, but Klauer made it.  

So the two photos at the top of the post are Oshkosh Extreme Runway System units aka XRS.  For Canadian airports these seem the right stuff.

All photos by Will Van Dorp, who occasionally slurs his title to truckster.
