How did you discover trains? I was four, and my grandpa “Pop” enjoyed taking me for walks. Pop’s house in New Rochelle, New York was a walk from a bridge over the New Haven Railroad’s four track electrified main line. Once there, I peered through the fence, intently watching for a headlight in the distance. I was soon able to identify a “local” on the outside track and an express. We went to the bridge as often as I could convince Pop of the need to go, and never left until we saw at least one New Haven train.
