I grew up in Berwyn, Illinois, USA, a suburb of Chicago. Two railroads ran through town: Chicago, Burlington and Quincy (now BNSF) and Illinois Central (now CN). As kids, we would ride our bikes down to the BNSF line to watch trains. This is a 3-track line known as the racetrack. Plenty of trains: Commuter rail, long distance passenger, and of course freight trains as well.
Two more childhood memories:
When I was about 5 years old, our upstairs neighbor was a driver for the Indiana Harbor Belt. One day he took me to his workplace to see what he drove. It was a steam loco in the final days of steam.
When I was around 10 years old, my uncle took me to go fishing on the Fox River, north of Aurora, IL. But we didn't go by car, we took the train, which was the Chicago, Aurora, & Elgin, an electric interurban line. Like so many railroads of its kind, the rise of automobile use reduced passenger counts and it became defunct in 1961,
