We had a very large Pere Marquette and Chesapeake and Ohio yard near where I grew up in Wyoming, Michigan. Huge roundhouse and blacksmith shop. A lot of the kids I grew up with worked in the yards and one buddies dad was Yardmaster and buddies older brother wound up Yardmaster after his dad retired. Several folks were killed or injured there every year
We kids knew all the engineers and their engines. We watched as the old steam engines gave way to the diesels. We hopped freights and road for 20+ miles over to Holland, Mi. on Lake Michigan and then hook a freight back home. RR bulls were always chasing us and we knew many of the hoboes and bums who road the rails. There were a couple of camps along a creek and the Grand River that ran nearby. Some of those guys were pretty scary.
As I think back my childhood in the late 40's and 50's was a shining time. We had the train yards, a couple huge dumps to pick and to shoot rats, a creek and a river to build and ride home made rafts and fish, Gypsum mines that ran all over the place and gypsum strip mine ponds to swim, fish, trap, play hockey on in the winter along with the bottom lands, meadows and woods to play army and cowboys and Indians, and later to hunt small game. There were nearby hills to ski and sled in the winter as well as steep streets in the hills to run our home made carts down. There was the huge excelsior plant nearby with millions of logs piled into huge pyramids. Two spectacular fires there and lots of logs to swipe to build our rafts and build our camps.
