Whilst folks are hijacking the thread to mention CN can I throw this handgrenade in?

It's a CN SD40-2W in deplorable condition at Squamish BC.
Even though I have a suitable shell I'm not skilled or brave enough to try and replicate it
One detail to note here is the engine intake snow cover which is common on CN and I think some CP units, I've a faint inkling SP might have fitted a handful and UP has some on their snow clearing units over Donner which I think might have been Ex SP units.
Something else I've just noticed and that's a door on the conductors rear side of the Canada cab, note notch in snow cover to allow door to fully open and depressed handrail to clear the door handle. I've not spotted that before and assumed they were like all other cabs with the brake mans seat tucked up in that corner.
Note also the end steps, they're of the 'ladder' type at both ends, I.E each rung is directly above the one below, typically Phase II engines had 'staircase' steps (the lower one juts out below the one above) for safety reasons. Tunnel motors have staircase at the front and ladder at the rear, simply because of the extended radiator section didn't allow enough space for a staircase type on the rear.
It looks like (quick scan of photos) both CN and CP opted for ladder type steps at both ends on their SD40's I'm going to make a best guess it's for climate reasons as vertical steps will accumulate less packed snow. Interestingly, even the CP rebuilt Eco SD40's still retain the ladder type, I would have thought staircase was a mandate now.
Both of Richards CP and SP units look to have the correct tooling for the steps specific to those two Railroads/units, more often as not you'll see staircase units painted in Canadian colours and that's your lot.
One further diversion whilst scanning CP units was this Elephant ear fitted unit, I'd have wagered heavily on SP had these and I'm not sure how many were fitted or for how long; but it opens up a little diversion from the run of the mill CP units.
