PlayStation Shs: 395 Ai Trains Have Different Traction Motor Sounds

As the title says, all AI driven class 395 trains have a different traction motor sound,
to the one being driven by the player.

The AI Trains have a much harsher, and much louder sound under acceleration and braking. I have also tried this as a passenger and the same result occurs; a very different, much louder sound.

The same applies whether under DC 3rd rail or overhead power.

Platform: PS4 (non pro).
