There's no way to view this in-game and it's unlikely to be added back in again. Information is definitely outdated and you shouldn't really take it to heart.
Buses were an old feature in Stepford County Railway which has little evidence left now.
Buses were free models used by SCR. They could be spawned at Stepford Town (now Stepford Central).
They were removed a couple days after SCR opened as there was no point. There were no roads at the time for the buses to drive on. The buses were also very glitchy, unpopular, and overall broken.
The buses were such an old feature that many users do not believe they were in the game.
