Southern Tennesean in 1952

Got back into my father's photographs last night and had to scan this one, even though the image is a little soft.

It is one of Southern's DL107s or DL109 leading train #45 The Tennesean at Bistrol VA.

Does anyone know if the engine can be identified? I know the DL107s were delivered with the fancier paint scheme, but after WWII they were probably repainted to this one. I also, don't know what paint scheme the DL109 came in.

Here's at least some more info on the DL units.

I may be wrong, but I think the DL109's had the headlight lowered?
