History

6-car 70-000 series set in December 2002

The trains were originally formed as 4-car (lengthened to 6 cars from 2002) sets for use on the Rinkai Line only, but 10-car formations were also delivered from 2002 for use on through services to/from the JR Saikyō Line. From October 2004, the fleet was reformed entirely as 10-car trains, with six surplus cars sold to JR East to create 209-3100 series EMUs used on the Kawagoe Line.[2]

209-3100 series conversions

JR East 209-3100 series set 71, April 2005

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]
