Peoria and Pekin Union Railway

The Peoria and Pekin Union Railway (reporting mark PPU) is a switching and terminal railroad in Illinois that began operating in 1881 and they opened a roadhouse in 1882.

[1] The railway managed hourly passenger travel, but ridership declined during the Great Depression and service was suspended on 7 November 1931.

Since the late 19th century, many railways have chosen to end their lines near Peoria, Illinois.

P&PU engines are responsible for picking up the cars at the end of other railways' lines and bringing them back to the main yard in East Peoria.

After these new trains have been formed, P&PU engines take the cars to the beginning of that rail line where they will continue their journey.
