Design

In 1985, the 6050 series design was created by rebuilding former 6000 series EMUs (dating from 1964) with new steel bodies. Before through-running operations began on 9 October 1986, the trains were required to satisfy fire resistance regulations due to the long tunnel on the Aizu Kinugawa Line.

Livery

Trains are painted in "jasmine white" with "sunny coral orange" and "purple ruby" lining.

History

All 44 former 6000 series cars were rebuilt between September 1985 and October 1986 as sets 6151 to 6172, with the first sets entering service on 15 November 1985. With the popularity of the new trains, an additional eight new 2-car sets were built, including one set for the Yagan Railway, enabling all "Rapid" services between Asakusa and Shimo-Imaichi to be increased to 6-car formations from the 9 August 1988 timetable revision. A further two newly built sets were added to the Yagan Railway fleet coinciding with the start of Aizu Kinugawa Line services. One additional new set was delivered to the Aizu Railway in 1990. Two 6050 series sets, 6177 and 6178, were rebuilt in September 2012 at
