At night I hear a train whistle where I live, only occasionally and actually rarely. Have heard it about 3 or 4 times in about 7 years.
Thing is I live about 7 miles from a train track. Is it possible to hear a train whistle that far away?
and it does sound kind of ghostly, echoey, resonates.
I wondered if anyone else hear knows how far a train whistle can be heard.
I live in Phoenix Az, by Camelback Mountain.
I sometimes hear one very close to here. Usually around noon.
I finally found out what is was. A neighbor who lives about a mile away, has a construction business and he also has an old steamboat whistle. I think he blows it to signal but maybe just for his amusement.
There are oddities about sound travel. I live about 300 yards from a rural crossroads. One day I was sitting on the porch and there was some construction work going on there. They were repairing a flashing red light.
I was sitting on the front porch and could hear their conversation as if they were only around 20 feet away.

Troublemaker! I'll bet you're a Doppler gangster.
LOL! We’re exactly the same here.
Before the highways and noise of modern life, Niagara Falls could be heard in Toronto roughly 70miles away.
..."Old Pa...it's coming!"
Barometric pressure...
When the pressure is low, (potential rain), it's like a lid was put on the atmosphere and pressed down...Everything goes sideways instead of up, including sound, and smoke...
Coyote hunters. Coyotes respond to train whistles
I’m sorry. I thought a Doppler Shift was an optional transmission on my 68 Oldsmobile.
I'd say flies, crows don't like to walk very far.....
I hear a train all the time from farther than that. Perfectly normal
Today's diesel locomotives do not have whistles. They are equipped with air horns.

As many folks have stated on here, yes it is possible to hear train horns from many miles away depending on weather conditions and the terrain features between you and the railroad.
Exactly.
When I can hear the trains on the tracks miles away it means rain soon.Train sounds not heard here in clear weather.
I take offense at that. Some of my best friends are drunk women.
The wind direction is not a factor (sound waves travel much faster than the air can). It is the temperature profile in the air above ground level which causes ducting of the sound energy, and is the biggest factor.
100 miles. You can hear the whistle blow 100 miles.
LOL I could have worded it better couldn’t I......had to go back and reread my remark. Your good to catch that...
I told my Olds dealer that I couldn’t find my Doppler shift but he told me where to stick it.
