History

Four 4-car trains were originally built and entered service in 1996 when the Rinkai Line opened between Shin-Kiba and Tokyo Teleport. A fifth train was built in 1999 for service expansion, and a sixth was built in 2001 for the extension of the line to Tennōzu Isle. In 2002, for the opening of the entire line to Ōsaki, the first five trains were extended to 6 cars, the sixth train was extended to 10 cars, and four new 10-car trains were built, for a total of five 6-car and five 10-car trains. The 10-car trains were also used on through services to/from the JR Saikyō Line.
From October 2004, the five 6-car trains were reformed as three 10-car trains. Six new trailer cars were built for the conversion, while six surplus cab and motor cars were sold to JR East to create 209-3100 series EMUs used on the Hachikō Line and Kawagoe Line.[2]
209-3100 series conversions
Six former 70-000 series cars were converted in 2004 and 2005 to become 209-3100 series EMUs for use by JR East. The subsequent identities of these cars are as shown below. (The former car numbers were reused when other spare cars were renumbered.)[2]
