Tokyu 5000 series


The Tokyu 5000 series is an electric multiple unit train type operated by the private railway operator Tokyu Corporation since 2002 on many of its commuter lines in the Tokyo area of Japan.

Design

First introduced in 2002, the design is based on the JR East E231 series commuter train, also manufactured by Tokyu Car Corporation 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, and information of the individual cars. This touch screen computer can also control interior temperature and lights.

Variants

These are ten-car sets first introduced on the Den-en-toshi Line from May 2002. These sets are distinguished by a green stripe above the doors. Six-door cars were inserted into some of the sets between 2005 and 2007, with sets 5105 onward having three 6-door cars per set. The 5000 series is fitted with CS-ATC and Tobu ATS 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 eight-car 5000 series sets were formed from 2009 using trailer cars displaced from ten-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.

Livery variations

Toyoko Line eight-car set 5122 received an all-over green vinyl wrapping livery in September 2017 to mark the 90th anniversary of the opening of the Toyoko Line and recreating the appearance of the original 5000 series EMUs nicknamed "green frog" which formerly operated on the line. It is scheduled to carry this livery until the end of August 2018.

5050 series

These are eight-car sets introduced on the Toyoko Line from April 2004. These sets are distinguished by a pink stripe above the doors. They are similar to the 5000 series, the only difference being that they have eight cars, and that they have the pink stripe instead of green. They are based at Motosumiyoshi Depot, and are capable of running through the Minatomirai Line. The 5050 series is notable as being the first type of train in the world to feature full-color LED destination indicators.
One set, 5155, was scrapped in July 2017, following accident damage sustained in 2014.

''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.

The train is equipped experimentally with free WiFi. One stanchion in the train features an embossed heart design as a whimsical way to brighten up commuters' journeys.

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. The second 10-car set was delivered from Tokyu Car in June 2011.
Set 4101 entered revenue service on the Tokyu Toyoko Line from 9 September 2011, reduced to an 8-car formation.
From 10 September 2012, 10-car 4000 series sets entered revenue service on the Seibu Ikebukuro Line and Tobu Tojo Line, with inter-running through to the Tokyo Metro Fukutoshin Line and Tokyo Metro Yurakucho Line.
