Working on the Railroad

I was walking along when I saw all these men on the train tracks. I stopped in my tracks. Someone was blowing a whistle in some sort of code. Everyone scrambled to the sides. It's something that you don't see or hear very often. All of sudden the crossing bars came down and bells started ringing and SWOOSH! This train zoomed by.



Trains come through every couple of minutes or so. It must take them a long to get a job done.
