I love how well those 700s have carried their paint.  The orange air conditioner though, ugh!   Don't get me wrong, I like seeing the warbonnets in any capacity, but like them better when I can shoot the engineer's side!

The different way they've mounted the PTC antenna farms is interesting. One is on the flat top of the roof and the other is on the angled section, like they were concerned with overhead clearances.

Very cool series!

Without (Googling) it, the way I understand/remember it... The angled "gull wing" roof profile the late ATSF adopted/requested was due to the close clearances issues of a coal mine loading situation out west somewhere at the time. (Evan Werkema will expectedly chime in below). Now 25-30 some-odd years later, where the lowest-bid third party contractor bolts on the FRA mandated Positive Train Control antenna units, have been literally at the whim of the man with the screw gun. I'm patiently waiting for nose mounted equipment....

I believe the close clearance cab roof profile was for the loader at the York Canyon coal mine.

I've had numerous encounters with 710. The last time was on a H-BARPAS9-20A, that I dogcaught at Oroville and brought up to Keddie on February 22, 2024. Here it is at the east end of Pulga siding un UP's Canyon Sub (California, USA, planet Earth). I seem to recall that for its age it seems to still run fairly well despite the atrocious condition of the cab interior.
