The very first thing I noticed when firing up my old routes to see how they look in TSW3 was that the snow underneath the coaches on Arosalinie is flashing brightly, on and off like it's lit up. It lights up as a solid segment too, and the effect moves down the train. Video: https://1drv.ms/u/s!AmUam9bd9z-N7H94r4PtGLijaBpZ
