The Tokyo Waterfront Area Rapid Transit 70-000 series (東京臨海高速鉄道70-000形?) is a DC commuter electric multiple unit (EMU) train type operated in the Tokyo area of Japan by the Tokyo Waterfront Area Rapid Transit. The train was built by Kawasaki Heavy Industries and first entered revenue service in 1996. Its design is based on the 209 series.
As of 1 April 2011[update], eight 10-car sets, numbered Z1 to Z8, are based at Yashio Depot in Tokyo (accessed via a spur located between Tennōzu Isle Station and Tokyo Teleport Station). The sets are formed as shown below, with car 1 at the Ōsaki end and car 10 at the Shin-kiba end. Trains consist of six motored "M" cars and four trailer "T" cars.
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.
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.)
