I don't see any "screens" on the boxes, which makes me doubt filters. I noticed that the other loco in the photo also has the same "boxes". There is a remote possibility that these are part of some remote control system, especially if these are recent photos. Other than that, I have no clue.

The greatest place to live life, is on the sharp leading edge of a learning curve.
Lead me not into temptation.....I can find it myself!
