The Elkhart and Western Railroad (reporting mark EWR) is a Class III short-line railroad operating in and around the city of Elkhart in Elkhart County, Indiana, and is a subsidiary of Pioneer Railcorp.
Pioneer Railcorp (reporting mark PREX) created the Elkhart and Western on May 1, 2001 from a 10-mile (16 km) stretch of the Michigan Southern Railroad. The line begins at its junction with the Norfolk Southern Railway near the center of Elkhart, then crosses the St. Joseph River which it follows westward, and finally ends on the northeast side of Mishawaka in neighboring St. Joseph County.
Freight hauled on the E&W consists mainly of auto frames, lumber and cement.
The EWR received its two locomotives from Pioneer Railcorp, and although the units no longer have the Pioneer reporting marks the units are still owned by EWR's parent.
