    Possibly.

    Some electric model aircraft speed controllers play tones/ beeps by vibrating the armature to indicate the state of programmable features.

    :smile: Yes indeed charming. And with electronic controls, very believable.

    Changing the frequency of firing rates as a function of speed is like shifting gears in a transmission.

    I imagine that an alien from a world with only electric drives would be charmed by the sounds of a Harley accelerating. :wink:

    Montreal subways play a pleasant four note sequence on starting. Well, in mid 80's they did. Sigh, seems like only yesterday.
    Of course they're way smaller machines.

    So yes i believe it's real...

    I'm still not convinced. I've watched several other videos of the train, and although the notes do change, they are all monotonic. Either someone has "layered" the sound track in a clever way, or someone has added an acoustic system to augment the trains natural tones. In either case, I think it is a pleasant effect, and if not real, it should be added to all electric commuter trains.

    Our local e-commuter train used to routinely run over people when it first went into service.
    It's name quickly evolved from MAX(Metro Area eXpress) to Mad Max.

    Actually, listening to the following, I just realized that if two trains were leaving at once, it might create the same effect. But I think the timing would have to be perfect to get them to make harmonious music, as in Dave's video.

    ps. If anyone is really bored, you can watch the following.
    14 ½ minutes of listening to LOTS of these trains leave the station.



    I could only make it through the first 3 minutes.
