The Tokyu 5000 series (東急5000系, Tōkyū 5000-kei) is an electric multiple unit (EMU) train type operated by the private railway operator Tokyu Corporation since 2002 on many of its commuter lines in the Tokyo area of Japan.
Contents
Design
First introduced in 2002, the design is based on the JR East E231 series commuter train, also manufactured by Tokyu Car Corporation (now J-TREC) in Yokohama.
All trains are equipped with interior LCD screens, displaying the station names, and automatic announcements in both Japanese and English. The 5000 series uses blue seat moquette fabric, while the 5050 and 5080 series have red seat moquette.
Driver's cab
All sets use the same driver's cab, with a gray color, and a single 'T' shaped brake and throttle controller. There are four throttle steps, and seven brake steps. The speedometers are equipped with ATC. To the right of the speedometer is an information screen, showing the run type (local, express, etc.), and information of the individual cars. This touch screen computer can also control interior temperature and lights.
Variants
5000 series
These are 10-car sets first introduced on the Den-en-toshi Line from May 2002. These sets are distinguished by a green stripe above the doors. 6-door cars were inserted into some of the sets between 2005 and 2007, with sets 5105 onward having three 6-door cars per set (cars 4, 5, and 8). The 5000 series is fitted with CS-ATC and Tobu ATS (TSP) in order to run through the Tokyo Metro Hanzomon Line, and onward over the Tobu Skytree Line to Tōbu-Dōbutsu-Kōen, Tobu Isesaki Line to Kuki, and Tobu Nikko Line to Minami-Kurihashi. These sets are based at Tokyu's Nagatsuta depot, and are powered by Hitachi motors with VVVF inverters.
Four 5000 series sets (5118, 5119, 5121, and 5122) were formed from 2009 using trailer cars displaced from 10-car sets by newly built six-door cars. These sets have the same pink stripe above the doors as the Toyoko Line 5050 series sets.
New four-door cars were built from December 2015 to replace the three six-door cars in each set to ensure uniform door-spacing ahead of the introduction of platform edge doors at Den-en-toshi Line stations from 2016. All six-door cars are scheduled to be replaced by the end of fiscal 2017. The new cars added incorporate a number of interior design improvements, including higher seat backs and headrests on some seats.

The sets are formed as follows.
Den-en-toshi Line set 5101

They are based at Motosumiyoshi Depot, and are capable of running through the Minatomirai Line.

Shibuya Hikarie
Set number 4110 was delivered in April 2013 in a special Shibuya Hikarie body graphics and with modified interior to mark the first anniversary of Tokyu's "Shibuya Hikarie" development located above the newly expanded underground Shibuya Station. This trainset entered revenue service on 26 April 2013. It is the first 5050 series train to feature LED interior lighting, and has higher backed seating than regular trains, with grey seat backs in cars 1, 3, 8, and 10, brown seat backs in cars 2, 4, 6, and 9, and blue seat backs in cars 5 and 7.

History
Nine cars of the first set were delivered from Tokyu Car's Yokohama factory to Tokyu's Nagatsuta Depot in Kanagawa Prefecture between 29 and 31 March 2011. These cars were formed into a 10-car set with the inclusion of intermediate motor car 4601, renumbered from former 5050 series trailer car 5469, which was itself previously renumbered from motor car 5918.
