Derby Junction


Derby is a tiny town where the original Illinois Southern Rwy and the MR&BT crossed. Once merged, the M-I maintained a 2-track yard at this important location. The Junction served as an interchange point between the predominantly east-west Ste Genevieve subdivision and the predominately north-south Bonne Terre (BT) subdivision serving the Old Lead Belt.

Layout adaptation…

The layout has a run-around and a 2-track staging yard which serves as the terminus for point-to-point operations. Beyond Derby [off-layout] lies Bismarck, the end of the line for the Ste Genevieve Subdivision.
