That appears to be a photo of a model, thus it is sort of difficult to tell. However, the frame outlined area, is obviously for the top portion of the winterization hatch, which I'm pretty sure ALL E8 and E9 units had as built. 

Is it possible to post top views of prototype E8/E9 units?

Although I am fairly familiar with the Winterization Hatch function, I must admit that I am NOT aware that any of them could be remotely controlled by any sort of "servo". That lever on the side of the Winterization Hatch, had two positions, i.e. "SUMMER" and "WINTER". That aside lever was to lock open the shutters in the top of the Hatch assembly, for "SUMMER" operation, then lock the shutters closed for "WINTER" operation. With the shutters closed, the heat from that one cooling fan would then be blown downwards and into the engine room, which tended to keep things from freezing up, plus provided warmer intake air for combustion.

EMD continued to offer the Winterization modification, in various forms, on locomotives even up thru the SD60s. However, I never once saw any "remote servo" operation for the shutters in the top of the Winterization Hatch.

Thanks for info on the lever, as I had never seen the lever before.  Looks like not many units had them installed.

As far as I know, ALL E8 and E9 units were built with the Winterization Hatches, then the UP added their own design "Snow Shields".

Yea but what about the levers.  Now that I know they exist, I have only seen them in a handful of pictures.

All Winterization Hatches would have had the levers. The lever had a large bolt hole in the end, so that the bolt would be tightened and thus keep the lever in the desired position.

Since those photos don't really show the side of the hatch, it is pretty difficult to tell. On the other hand, it looks to me like the internal shutter arrangement has been removed, with only expanded metal screening now mounted in the square hatch opening. If that's the case, the the levers would have also been removed, since there would be no more shutters to control, i.e. the unit shown is perpetually in the "SUMMER" mode.
