Back in the day, we'd make
frequent trips with the
family from our home in
Austin to our
grandmother's house in
Lubbock. One time, we were
greeted with a
blast from the horn from every
train that passed us.
Years later, we kids realized that, by blind chance, every train we passed was approaching a railroad crossing at the time, and they were required to sound their horn when they were coming up to a crossing. But when we were young, it seemed obvious that all the engineers recognized our car and were blowing the horn to say hello to us.
It was very exciting to know that all the engineers and conductors were so friendly.
