Front 6-wheel truck looks to be from an SD70ACe.

Aggressive-looking piece of equipment!

The lead truck is the EMD Radial Truck (cast version), common to the 70 series, not just the ACe.
  | 
That is actually the original HTCR Radial truck or HTCR 1 version seen on all SD70MACs numbered 9400-9775 and all of the Santa Fe/BNSF SD75Ms numbered 200-250 and 8251-8275.

Are all five axles powered or is there an idler in there somewhere?

Don't think it's se;f propelled. Lots of open space in those trucks. The rotaries need lots O horsepower to spin the auger and throw the snow far enough. Like UP's big ones that were 3000hp and still could have used more.
