Place it at the start of a train arrival sequence, before any station ambience or departure chatter, then follow it with the Inception Horn and a Pop Sound Effect to mark the cut to the platform view.

This 1.7-second clip is the horn of Renfe's AV01 high-speed train, a short, sharp blast with a clear, ringing tone. It feels urgent and attention-grabbing, like a fast train announcing its arrival, and it works best as a sudden signal rather than background noise. The sound comes from the AV01 unit as featured in Trainz Mobile and Trainz 2012.
