The Elkhart & Western Railroad Co. (reporting mark EWR), a wholly owned subsidiary of Pioneer Railcorp (reporting mark PREX), is a Class III short-line railroad operating three unconnected lines in northern Indiana, United States.

Freight hauled on the EWR Elkhart Line consists mainly of plastic flakes, lumber, paper and cement.

Freight hauled on the EWR Argos Line consists of mainly scrap iron, paper, plastic pellets, and lime, with the addition of storage car holding.

In January 2018, CSX sold 9.58 mi (15.42 km) of track running from Monon to Monticello, to ETW.

Operations began in August, serving the only customer on the line, Monticello Farm Service, Inc.[1] 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.
