Most sounds change in response to the activity of the item generating the sound. Factories for example don't generate the factory sound when not running. The station has a clicking sound which seems to click in exact timing with the light going on and off when the train is in the station. Once a train leaves the station, the light becomes solid, but the clicking sound continues. Maybe not a game breaking bug; just immersion breaking. The other thing I noticed is that station's lights are powered even if no electricity is present.

Thanks for the report. However, the sound is completely unrelated to any state on the station. It just plays as long as the station exists. The light is also completely unrelated to power; the entity does not use power.
