The Tokyu 8500 series (東急8500系 Tōkyū 8500-kei?) is a commuter electric multiple unit (EMU) train type operated by the private railway operator Tokyu Corporation on the Tokyu Den-en-toshi Line and Tokyu Oimachi Line in the Tokyo area of Japan since 1975.[1]

Design[edit]

First introduced in 1975, the design is based on the earlier 8000 series design.[2] A total of 400 vehicles were built by 1991.[1]

Operations[edit]

The 10-car trainsets are primarily used on inter-running services on the Tokyu Den-en-toshi Line, Tokyo Metro Hanzomon Line, Tobu Skytree Line, Tobu Isesaki Line as far as Kuki, and Tobu Nikko Line as far as Minami-Kurihashi.[3] The five-car sets are used on Tokyu Oimachi Line services.[3]

Formations[edit]

Den-en-toshi Line 10-car sets[edit]

As of 1 April 2014, the fleet consists of 26 ten-car sets, based at Nagatsuta Depot, and formed as shown below with eight motored ("M") cars and two non-powered trailer ("T") cars, and car 1 at the Shibuya end.[3]

  • Cars 2, 5, 7, and 10 are each fitted with one lozenge-type pantograph.[3]
  • Cars 3 and 9 have a wheelchair space.[3]
  • Car 2 is designated as a mildly air-conditioned car.[3]

Den-en-toshi Line sets 8601 to 8614 were marked with "K" stickers on the center front window of the driving cab ends, and they were restricted to operating on Den-en-toshi Line and Tokyo Metro Hanzōmon Line only, due to lack of Tobu ATS on these sets. After the opening of the Hanzōmon Line extension from Suitengūmae Station to Oshiage Station, sets 8601, 8602, 8613, and 8614 were fitted with Tobu ATS, allowing them to operate on Tobu Skytree Line, Tobu Isesaki Line and Tōbu Nikkō Line (and had their "K" stickers removed), while sets 8603 to 8612 were retained without Tobu ATS until their retirement from duties on the Den-en-toshi Line.

Oimachi Line 5-car sets[edit]
