A question for train lovers (a specific part of a steam locomotive)

I am currently translating a text concerning steam locomotives (from Slovak to English) and I am a little bit stuck on an issue with a certain part of a steam locomotive (in the red circle).

Is there a specific name for that part? Like some kind of plate which helps to rectify the steam?

My second question is directly connected with the first one. Thanks to this particular part, the locomotive got its name, with these parts symbolizing "ears", therefore, the locomotive is called "Ušatá" in Slovak, which can be literally translated as "The one with ears" or "The one with big ears". Is there a word in English that would perfectly describe this attribute?

Any kind of help/answer will be much appreciated. :)

Solution 1:

According to the English Wikipedia, they are called smoke deflectors:

Smoke deflectors, sometimes called "blinkers" in the UK because of their strong resemblance to the blinders used on racing horses, are vertical plates attached to the front of a steam locomotive on each side of the smokebox. They are designed to lift smoke away from the locomotive at speed so that the driver has better visibility. [link]

(I guess the "blinkers" idea would be analogous to the Slovak "ears" image that you mention.)
