I tend to go down the yoo toob rabbit hole on videos related to railroading.

One thing I noticed on some engines is a circular device on the windshields. At first I thought is was a fan of sorts by virtue of the round shape.

Saw an image from my latest viewing from the inside cockpit. Whatever this device it, it appears to keep the windshield clean compared to the outer part.

This is my question: is this some type of 360 degree rotating wiper?

Yes and some ships also have this.

They're "spin windows" or "clear view screens" and are used in a few other applications as well, such as ships and CNC machine tools. Essentially it's just a round piece of glass or clear plastic that's spinning very quickly, fast enough that any water that gets on it is immediately flung off. There is no wiper blade involved.

Aha! ...that makes sense because I do not see any wipers.

Apparently it must spin fast enough that freezing snow or rain cannot build up on it.

...thanks for the info.

I like watching the snowblower and plow trains, saw a couple where the snowbanks just stopped the train dead in its tracks.
