Four Leslie S5TR airhorns (the fifth is broken off) atop a Union Pacific locomotive built by General Electric, eastbound at Duplainville, near Waukesha, Wisconsin. The photographer was the engineer for the Milwaukee Road train being pulled by the UP locomotives. Closeups of airhorns are unusual, and made possible only because the train had stopped and the engineer/photographer climbed on top of his locomotive. The train appears in a tidy Waukesha County landscape, with mowed lawns in evidence. The Duplainville Tower is in the background. Waukesha County, west of Milwaukee, was a rapidly developing suburban area in the 1970s. A stopped train with a broken airhorn had "not in my back yard" potential, and demonstrates the tension between historic transportation methods and suburban notions of private property ownership.
