The snow kick-up effect on oncoming AI trains on SEHS is flickering between two tones of grey. Perhaps a side-effect of the snow being illuminated by my headlights? The kick-up effect on my train seems to be normal (although I haven't checked how my own snow kick-up looks with an oncoming AI train).
The flickering seems to be related to the speed of the train who's snow is being kicked-up. Just had an oncoming AI-train slowing down for a station stop while I was already stopped at the station, and it seems it flickers once for every coach of the AI-train. Flickering frequency slowed down as the AI train slowed down.
