Green Car introduction

In April 2018, JR East announced plans to add two bilevel Green (first class) cars to 58 ten-car and six-car E233-0 series EMU sets operated on the Chūō Line and through-service trains to the Ōme Line, and to install toilets on these sets ahead of Green car introductions. To compensate for train shortages brought on by toilet installations, a new ten-car set (T71) was delivered from J-TREC's Yokohama facility on 11 June 2020. The Green cars will be positioned as cars 4 and 5 in the newly formed 12- and 8-car sets. Green car services were initially due for introduction in fiscal 2020, but this was deferred to 2023. On 27 April 2022, JR East announced that Green car introductions would again be postponed until the end of fiscal 2024 or later as a result of the global chip shortage. The first Green cars, SaRo E233-1 and SaRo E232-1, were delivered from J-TREC's Yokohama facility from 12 July 2022. These cars use double-leaf sliding doors with a width of to allow for reduced boarding times at stations; previous designs were built using single-leaf doors with a width of . Test runs of the new Green cars are being conducted as of July 2022, starting with set H57.
