Railroad crossings

I live near quite a collection of railroad crossings. Normally the sound
of them crossing an intersection isn’t a big deal (I can usually sleep
through them) but occasionally it seems that whoever runs that horn gets
upset. The normal two short blasts before crossing becomes five really long
ones. These are enough to blast myself, my husband, my daughter, and my dogs
awake. Do the number and/or duration of blasts mean anything, like “idiot get
off the tracks!”? Or are we at the mercy of a guy who wants to make sure
everyone is awake the same time he is?

Yes, the whistles mean something.
Lookee here;
That being said, this is a question. Belongs in GQ.
Welcome to the SDMB.

Off to GQ.
