or they could be ghost trains . maybe your house or apartment was built over deserted train tracks
wow. spooky idea. just got called into work, darn, these answers are fascinating!
I’m more or less, maybe less than 7 miles but more than 4, and not as the crow flies, but still over 4 miles away.
ghost train...hmmm, it is awfully spooky. Heard it at midnight, why would a train whistle blow at midnight? I read that in Tempe they actually made a law they can’t blow the whistle because of complaints.
Tempe is run by Democrats, of course;)
