The 50000 series is a commuter EMU operated by Tōbu Railway in Japan and manufactured by Hitachi to its "A-train" concept. The trains closely resemble the Seibu 20000 series EMUs, and represent the first use of aluminium body cars on Tōbu commuter trains. They are also the first Tōbu trains to feature bilingual (Japanese and English) automated passenger announcements.

[edit] Variants
[edit] 50000 series
Two 10-car 50000 series sets were built for use on the Tōbu Tōjō Main Line.
The first set (51001) entered service in 2005-03-16, followed by the second set (51002) in October 2005. The second set differs in having an emergency door in the front ends, and externally resembles the 50050 series used on the Tōbu Isesaki Line (see below).

[edit] 50050 series
The 10-car 50050 series sets were built for use on the Tōbu Isesaki and Nikkō lines, and inter-running services through the Tōkyō Metro Hanzōmon Line to the Tōkyū Den-en-toshi Line displacing the earlier 30000 series sets.
The first set (51051) entered service on 2006-03-18, and as at January 2007, 10 sets were in service. While broadly based on the Tōjō Line 50000 series design with emergency end doors, cars are 30 mm narrower (2,770 mm compared with 2,800 mm) to cope with reduced clearances on the subway lines.
[edit] 50070 series
The 10-car 50070 series sets were built for use on Tōbu Tōjō Main Line and Tokyo Metro Yūrakuchō Line inter-running services, and will also be used on inter-running services through the Tokyo Metro Fukutoshin Line from 2008.
The first set (51071) was delivered in early March 2007, entering revenue-earning service in July. It differs from earlier variants in having full-colour LED destination indicators, and is also equipped with ATO for subway operation.
A total of four sets were delivered by March 2008.[1]
[edit] 50090 series
Four 10-car 50090 sets were delivered in February and March 2008 for use on new Tōbu Tōjō Main Line limited-stop evening TJ Liner services starting from the start of the new timetable on 14 June 2008.[2] Internally, these trains feature rotating seats that can be arranged longitudinally for daytime services and in forward-facing transverse pairs for "Liner" services. Externally, the sets feature a blue waistline stripe running the length of each car, with a "TOJO LINE" logo.[3]
A public preview run of the 50090 series took place on 23 March 2008 from Ikebukuro to Shinrinkōen station, followed by a photographic event at Shinrinkōen depot.[4]
A 50090 series is also scheduled to operate on a special Nanamine express service on 20 April 2008 running from Ikebukuro to Ogawamachi.[5]
