I’m not an expert on F3’s, but yes, that is a winterization hatch on the fourth fan, and it almost looks like there is a second exhaust between the WH and fan 3 ?
It looks like the steam generator is in the B unit. The fans appear a normal height to me, you would have to ad the WH, lifting rings, horns, etc, to match this loco.
That looks like a standard 'ol F3 phase 2 with low fans. If you look closely in front of the winterization hatch, the second exhaust stack can be seen.
I’ve never seen a turbocharged F unit, but i guess anything is possible.
Those are B-units in the photo, not E’s. The last one is one of the 10 F3B’s with boilers that the UP had. The numbers, at the date of the photo, were likely:
900B,C
901B,C
902B,C
903B,C
904B,C
The second B doesn’t seem to be showing any rooftop boiler fittings.
The 1500-horsepower F7 differed from the 1500-horsepower F3 mainly by the installation of automatic transition, a 567BC diesel engine, and D47 traction motors.
Don’t know. But that’s the one Intermountain chose to “show off”.
Here’s a shot of an Athearn:
Mostly, the Intermountain just look “funny” to me. I would say that the Intermountain fans have too big a fillet around the fan base, and that there’s too much draft angle showing on the sides.
I can’t find a good shot of those fan shrouds, so I can’t say which is more correct. But they do look different to me.
And one could argue that since the Highliner shell is “officially” the best, then their fans should be, too.
