The Tokyo Waterfront Area Rapid Transit 71‑000 series (東京臨海高速鉄道71‑000形) is an electric multiple unit (EMU) commuter train type operated by the third-sector railway operator Tokyo Waterfront Area Rapid Transit (TWR) since 2025. A total of eight 10-car sets are to be built to replace the fleet of 70-000 series sets used on the Rinkai Line since its opening in 1996.[5]
Design
Based on the JR East E233 series design, the 71‑000 series is built by Japan Transport Engineering Company (J-TREC) as part of its "Sustina S24 Series" family of 20-meter-long four-door cars.[4] The type uses a wide-body design to reduce congestion.[6]
Formation
Sets are based at Yashio Depot and are formed as follows with six motored ("M") cars and four non-powered trailer ("T") cars.[3]
