Looks like a pair of ex CP B units,with the big winter hatch installed in that pic.
When Steam Rotaries were converted,the RR's ripped out the steam boilers and drive parts,
and placed 4 traction motors in the shell to power the wheel and 2 sets of controls,1 set controlled
the unit used to power the rotary's motors,and the 2nd set,the units pushing the plow.
That RSP38-2 likely has 6 motors,3 to spin the rotary wheel,then 3 motors in the HTC truck,will still need "pushers"
along when plowing in heavy snow
The Land of Enchantment is not Flyover country!
