Prototype…
Middle Yard sat roughly halfway between Thomure and the Ste. Genevieve depot—a distance of about two miles. The prototype contained twelve tracks with a total capacity of 139 cars, and a Fairbanks balance-beam scale stood at the yard’s south end. Crews used Middle Yard to classify cars and build trains for the southbound (largely westward) run from Ste. Genevieve to the Missouri Pacific interchange at Bismarck on the DeSoto Division.

Layout adaptation…
Middle Yard is equipped with three stub tracks for sorting and classifying cars, along with two arrival/departure tracks used to build and break trains efficiently.

The Yardmaster uses a Boulder Creek Engineering scale on Track 3 to weigh outbound loads. Any car found overweight is shoved to the end of the track and held for reweighing the following day.




The Yardmaster’s position stays busy—managing ferry cuts, weighing loads, and building several trains. Peerless White Lime, the M-I’s largest customer, is switched daily and sometimes twice, depending on car demand. The Yard Job handles Ste. Genevieve local customers and Frisco interchange traffic, while the Derby Junction Turn keeps bridge traffic moving along. And all the while, the boat continues its trips across the river.
