Burlington Northern General Electric U33C 5761 heads a southbound movement at Alpha, Illinois in August 1976. This unit was built in 1971 and retired in 1986. The train is traversing the BN's connecting link between its Twin Cities main line at Savanna and its western main line at Galesburg — a line known as the "Peavine" because of its frequent changes of direction due to having been formed from parts of several intersecting lines now mostly abandoned.
