The Sound Of The Train

I was raised with a traintrack in the backyard, and everyday, (at least 4 or 5 times a day)
a train would go by, sounding it's horn, and ringing the bell.  You wouldn't think it would
be a pleasant sound, but it always made me feel at home hearing it.  Even at night, when I was asleep and the train would roar, it was a sound that I didn't realize how much I missed
until I'd been away from it for a while.
