As written in subject, i have tested all tracks and roads when noticed - these tracks and roads have some shining pixles with special colors:
- continuosly welded 98 lb/y, 120 km/h
- continuosly welded 130 lb/y, 145 km/h
- steel track 109 lb/y, 160 km/h
- continuosly welded 113 lb/y, 200 km/h
- tar macadam road heavy 80 km/h, 8t
- all hot rolled asphalt roads
- all stone mastic asphalt roads
Pak128.Britain is not optimised for use with night view: it is very difficult to make a rendered pakset work well with the special colour system in Simutrans. Although night view does look splendid with a fully optimised pakset (such as Pak64, Pak128, Pak96.Comic), it is actually quite awkward to interact with the game in the night time, and I always used to turn it off even when using a night optimised pakset and have only the daytime. In Experimental, a day/night cycle that is out of keeping with the internal timing clock would be even more confusing.
For these reasons, fixing this sort of issue is an extremely low priority.
