Sooooooo... because I had nothing better to do today besides look up interesting things. In common with Otto Perry the guy who took the picture in 41 is my love for capturing images and I never only take one image.
I usually take 2 or 3. I was sitting here thinking that Otto probably did too. I went in search of another image of that consist and found it with #483 (destroyed in a roundhouse pit accident and scraped for parts) now on the head end and 480 as a helper and a few more tank cars. See it here. The dozers are clearly visible in this angle hit the zoom button in the upper right. Then just click the image it will keep zooming in. Those old large format cameras were great. https://digital.denverlibrary.org/digital/collection/p15330coll22/id/51769/rec/40 and this one as well,

I totally forgot about the scale of those flatcars. the search for different angles was a big help.

Isn't there some type of "structure" on the same freight car as the dozers.? It seems to go right down to the track frames.
Could they possibly be pipelayers.? Was that type of machine even around in 1941.?
I wondered that too

I see one shovel front and what looks like a crane boom . Ill bet theres a clam bucket in there. One machine rigged as a shovel ,one as a crane and a clam . With those dozers they look set to build anything . They didnt need much in those days to get things done.

G..G..G..Granville.........!! Fetch your cloth.
This maybe illustrates better what I was talking about. There are three sections of crane boom in the foreground but both tractors seem to have this attachment on them that looks as though it goes right down to the track frame. Both tractors appear to be the same but the feature stands out better on the rear one because the crane boom sections are not obstructing the view. That structure is why I originally thought pipelayer.

1941 was the last year Cat made the 1H and also the first year they made the 8R. It was a mid year shift. On both the fuel tanks while having rounded shoulders to not slope toward the back on top. I think the fuel tanks on the crawlers look like they could be Allis but not that familiar with 1941 and older models.

My guess is -2 Northwest cranes,, carbody's first ,2 track frames , in front of the boom sections is a 4 cyl. Murphy engine- while the dozer fuel tanks do look mighty like AC. just my 2c worth.
