    This isn’t quite true; the Doppler effect only exists when you’re at an angle to the approaching sound source. If you’re directly in front of it, the (apparent) frequency remains the same (until you get hit by the train), then it decreases as the train gets further away.

      That’s why I made sure to say the train was /accelerating/ rather than simply travelling at a constant speed towards Mr. Doppler. I may be wrong, but I think this would give you a shift.

    @Cameron Well they aren’t point masses, so Doppler isn’t *directly* in front of the sound source. Still, it’s a legit complaint.

    I did like this comic though.

    So assuming that this is indeed THE Mr. Doppler, should we believe that he miraculously evaded certain doom and lived to tell the tale? And report his discovery? :)

    It’s ok. In my mind that train is about to hit 88 mph and travel through time.

    Should be a nice anecdote to tell in the to-be published article:
    “(…) We found that standing in front of an accelerating train made the sound of said train appear to increase in frequency. To repeat this finding, we devised a simple experiment involving trains and PHD-candidates to (…) And we specially thank the contributing authors of this article. May they rest in peace.”
