Pioneer bought the line and its Evansville shops in 2000 from the Evansville Terminal Railway. However, when Pioneer stopped shipping grain, the track had to be dismantled and salvaged at the close of 2011.
The dates back to 1881 as part of the Evansville and Peoria Railroad, which then became part of the Peoria, Decatur & Evansville Railway through a series of purchases. The PD&E became part of Illinois Central in 1900. The ISW is currently the only remaining in-service segment of the PD&E south of Mattoon, Illinois.
