JR Shikoku 7200 series

The JR Shikoku 7200 series, branded the eco7200 series, is a Japanese outer suburban electric multiple unit operated by the Shikoku Railway Company since June 2016. These sets were converted from former 121 series two-car sets.
==History==
Converted from 121 series cars manufactured in 1987 at JR Shikoku's Tadotsu Works, the 7200 series is considered by JR to be a substantial rebuild of the 121 series cars as they were considered to be aging equipment by that time. The first set, R03, converted from 121 series set 003, was completed in March 2016; the first sets entered service in June that year.
All nineteen 121 series sets have been converted to 7200 series sets as of July 2019, with the last set to be converted, 002, becoming set R02 on 18 February 2019. All sets are in service and are based at Takamatsu Depot.
==Design==
The 7200 series' body style is identical to that of the 121 series sets they were converted from. The cars are unpainted and have red and green accents. "eco7200 series train" logos are seen splashed in front and on the sides.
==Specifications==
Construction and dimensions are identical to the 121 series cars. However, a major difference between the 7200 and 121 series is that the 7200 series utilize variable frequency drives; in this case, the 7200 series use two-level insulated gate bipolar transistor variable frequency drives manufactured by Tōyō Denki Seizō which have a rather melodic cadence. The 7200 series also utilize efWING bogies manufactured by Kawasaki Heavy Industries which save more energy than previous bogies due to a lightweight construction. The wheels have lime green flanges.
As of 2018, some sets have been fitted with LED headlights.
