Very nice, not overloaded set, which has always been missing. Well done! Thanks Erato
If you let me, I would have some suggestions:
1. Buffers for end stations
It could be as station fields, or as in CHIPS stations, where it would appear itself at the end of the station, where there are no further tracks.

2. Passengers at the station
Although I'm not a great eyecand player, this is a detail that definitely makes the game more enjoyable. Passengers are displayed at Japanese and Kiwitree stations (I don't know others). Especially in the case of Japanese it is interestingly done, where passengers "move" around the station. In Kiwitree, on the other hand, graphics are better suited to the number of waiting passengers - at the station you can already see a dozen or so passengers, you can also see when it expects 1000 and when 5000 passengers.
3. Set OpenGFX + on the station list to replace the original ones.
These stations are no different, so they could (?) replace the default.
4. Small roofs facing the other way
