The Tobu 50000 series (東武50000系, Tōbu 50000-kei) is a DC electric multiple unit (EMU) commuter train type operated by the private railway operator Tobu Railway in Japan since March 2005, manufactured by Hitachi to its "A-train" concept. The trains represent the first use of aluminium body cars on Tobu commuter trains. They are also the first Tobu trains to feature bilingual (Japanese and English) automated passenger announcements.
The first 50000 series set, 51001, was delivered in November 2004 and entered service on the Tobu Tojo Line on 16 March 2005, followed by second-batch 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 Tobu Skytree Line (see below). [1]
Two more sets, 51003 and 51004, were delivered during fiscal 2009. [2] 51003 was delivered to Shinrinkōen Depot in January 2010, [3] followed by 51004 in February 2010. [4] These two sets have pairs of opening windows and interiors based on sets 51061 onward.

The 10-car 50050 series sets were built for use on the Tobu Isesaki, Skytree and Nikko lines, and inter-running services through the Tokyo Metro Hanzomon Line to the Tokyu Den-en-toshi Line displacing the earlier 30000 series sets. [5]
The first set (51051) entered service on 18 March 2006, and as of January 2007, 10 sets were in service. While broadly based on the Tojo Line 50000 series design with emergency end doors, cars are 30 mm (1.2 in) narrower (2,770 mm (9 ft 1 in) compared with 2,800 mm (9 ft 2 in)) to cope with reduced clearances on the subway lines.
Sets 51061 onward have different seat covers and pairs of opening windows (like the 50090 series) instead of the large single-pane sealed windows on earlier units.
Three more sets (51066 to 51068) were delivered during fiscal 2009. [2]
From October 2012, set 51052 was modified with opening panes in four side windows per car, in the same style as Tojo Line set 51075 and JR East 209 series sets. [6]

Four 10-car 50090 sets were delivered in February and March 2008 for use on new Tobu Tojo Line limited-stop evening TJ Liner services starting from the start of the new timetable on 14 June 2008. [12] Internally, these trains feature rotating seats that can be arranged longitudinally for daytime services and in forward-facing transverse pairs for "Liner" services. These trains are also used on up "Rapid Express" services in the late afternoon and night as well as the newly introduced Kawagoe Limited Express services from 16 March 2019. Externally, the sets feature a blue waistline stripe running the length of each car, with a "TOJO LINE" logo. [13]

The 50090 series sets have seats that can be rotated and configured in longitudinal style for regular daytime services or in forward-facing transverse style for TJ Liner services and late afternoon/evening Ikebukuro-bound Rapid Express services. [18] When configured in transverse mode, the rows have a seat pitch of 1,000 mm (39 in). [18]
From 28 November 2015, 50090 series set 51092, based at Shinrinkoen Depot, received full-body vinyls recreating the dark blue with yellow stripe livery carried by 54 series and 53 series EMUs used on Flying Tojo limited express services on the Tobu Tojo Line during the 1950s. [19] The livery was commemorated with a special run on 2 February 2019, removed soon afterwards, and replaced with the "Ikebukuro - Kawagoe Art Train" livery.
Ahead of the 16 March 2019 timetable revision on the Tobu Tojo Line, 50090 series set 51092 was repainted from its previous "Flying Tojo" into a new art-based livery. The livery, designed by Koyano Yuuki, is designed to advertise the city of Kawagoe with the theme of "adding colour to Kawagoe". [20] The set was reintroduced into service on 12 February 2019, and was used on the first down departure of the new "Kawagoe Limited Express" train category operating on the Tojo Line since the 16 March 2019 timetable revision.
From 3 November 2016, 50050 series set 51055 received a yellow vinyl wrapping livery to mark the 25th anniversary of the cartoon character Crayon Shin-chan.
