	Some 4-car formations of 115-1000 series used in Okayama region were reduced to 3 cars by remodeling motored intermediate cars into the motored end cars in 2004. Although Japan National Railways (JNR) transplanted the cab section with the same profile as other end cars onto motored intermediate cars, JR West remodeled the intermediate cars into the end cars with leaving the body construction of the intermediate car in order to reduce the cost. So, the cab section design is gabled. Low front cab style is adopted to reduce remodeling cost. The refurbishment was also commenced with the same accommodation as 223-2000 series. 115-1600 series are used on the ordinary services of the Sanyo, Hakubi, and Uno lines.
