Fair enough, I won't be abe to check, however;
Rule 3: Don't build stations or station parts that serve the sole purpose of increasing the coverage area, sabotaging other players, increasing the station/town rating or decreasing the distance to another station.
Rule 12: No station spread cheating, e.g. transfers may not be done for the mere purpose of increasing the spread of a station.
With the above in mind, those bus stations whilst "NOT" connected to the main rail station are in themselves rule breaks.
But yeah Pariza does look like to be blatantly breaking Rule 4, so good spot.
Have a good day
