Tokyu 5000 series-Cedar Herald Index

The 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.

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, from which all cars in this series would be produced.

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.

5000 series

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. 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.

Initially six sets (5101–5106) were built between 2002 and 2003. Set 5101 was the prototype set and has slightly different dimensions (it is narrower than the other sets and has a slightly non-standard door spacing). Between 2005 and 2008, fourteen additional sets (5107–5117 and 5120–5122) were built with two six-door cars each (cars 5 and 8); sets 5117 and 5120–5122 were fully new built, while car 4 of sets 5107–5116 were surplus cars from sets 5102–5106, as two of their cars (5 and 8) were replaced with new six-door cars as well. Set 5122 never entered service on the Den-en-toshi Line. In early 2009, two additional sets (5118 and 5119) were built as 9-car sets (car 4 was missing, and cars 5 and 8 were six-door cars) but these also never entered into service.

Between 2009 and 2010, a third six-door car (car 4) was added to sets 5104–5117 and 5120 (total 15 sets): three cars were new built and 12 were taken from other sets (two cars each from sets 5102, 5103, 5118, 5119, 5121, and 5122). Of the 15 surplus four-door cars created, four were used to return sets 5102 and 5103 to fully four-door sets, six were inserted into sets 5118, 5119, 5121, and 5122, and the remaining five cars were used in 5050 series sets 5170–5172. Meanwhile, sets 5118, 5119, 5121, and 5122 were reformed as eight car sets and transferred to the Tōyoko Line. As mentioned earlier, nine-car sets 5118 and 5119 each had of their two six-door cars removed and replaced with two four-door surplus cars, and ten-car sets 5121 and 5122 each had two six-door cars replaced with a single four-door surplus car. In addition, a motored four-door car from each set was removed, and used in 5050 series sets 5169 and 5172–5174.

A total of 45 new four-door cars were built from December 2015 to replace the three six-door cars in sets 5104–5117 and 5120 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 were replaced by the end of 2017. The new cars added incorporate a number of interior design improvements, including higher seat backs and headrests on some seats.
