UP diesel with 3 windows on the side

[CS641]

Driving across Wyoming and noticed a UP diesel with extra windows on the side, appeared to be 3. Is this a special model? Sorry for not having a photo.

Thanks!

Like this? Two small side windows and a double-pane center?

Engine inherited from a pre-merger road?

Probably one of those, looks real close, just stuck out to me for some reason. I should have grabbed the cab #.

If that center window center divider happens to be a dark color, instead of light like in the link, it would look even more like 3 windows.
