The Script error: No such module "Nihongo"., branded Script error: No such module "Nihongo"., is a DC electric multiple unit (EMU) train type operated by East Japan Railway Company (JR East) in Japan. It was introduced into commercial service on 2 July 1993,[1] and was specifically designed to be used on limited express services from Tokyo to the Bōsō Peninsula.
Design
The trains were built jointly by Kinki Sharyo and Tokyu Car,[2] with a steel body design based directly on the earlier 253 series EMUs built for Narita Express services, although the window height was increased by 100 mm.[3] It is the first JR East limited express rolling stock to feature VVVF Gate turn-off thyristor traction control systems, based on the results of trials with the prototype 209 series commuter EMUs.[3]
DT56E bogies are used on motored cars, and TR241E bogies are used on trailer cars.[3]

History
The first two sets, Be01 and Be02, were delivered in March and April 1993, entering revenue service from 2 July 1993 on View Wakashio and View Sazanami limited express services.[4] Three more sets, Be03 to Be05, were delivered in October and November 1994.[4]
From the start of the revised timetable on 12 December 2000, the Green car (car 4) was made entirely no smoking.[4]
The destination indicators on the sides of cars were changed from the original roller blind type to LED indicators between October and November 2005.[4]
From the start of the revised timetable on 10 December 2005, View Wakashio and View Sazanami services were renamed simply Wakashio and Sazanami, and 255 series sets were also introduced on Shiosai services.[4] All cars were made no-smoking from this date.[4]
The front-end skirt design was modified during 2010.[1]
From 2014, the 255 series sets were retrofitted with IGBT-based traction control systems.[5]
Withdrawal
Initially, the 255 series sets were slated to be withdrawn from Wakashio, Sazanami, and Shiosai services before the start of the revised timetable on 16 March 2024,[6][7] however, their withdrawal from regular service was deferred until June 2024 with the last regularly scheduled Sazanami and Wakashio services using this series taking place on 28 and 29 June respectively.[8] They have since remained in limited operation for special services.[7] Set Be05 was withdrawn from service in June 2024,[8] followed by set Be01 in July 2024.[9]
