The ghostly trees at Peterborough - Doncaster are they in honour of Halloween or a permanent fixture?
The tops/top half of random trees in the foreground look as if they have been muted in colour and texture so they look greyed out then render into normal light as the train passes. There's a kind of example at around the 13 mins mark on this vid there might be other examples. it happens throughout the route. Sorry I don't have a better example. I experienced a similar phenomenon first on the peak district route on ps4. I've played the game on different screens and different systems and those are the only two routes it happens on for me so far. It could be a lighting conflict or some kind of side chain compression coming of the overhead cables or other foreground items. It's not game braking or anything just a curious anomaly. Looks a bit like it's not meant to be there and let's down slightly for me an otherwise visually impressive route. It doesn't bother me so much but does occur quite a bit throughout the route.
