The Sotetsu 11000 series (相鉄11000系) is an electric multiple unit (EMU) commuter train type operated by the private railway operator Sagami Railway (Sotetsu) in Japan since June 2009, replacing aging 5000 and 7000 series trains. Based on the JR E233-1000 series design, cars have four pairs of sliding doors per side.
As of 1 April 2016[update], the fleet consists of five ten-car sets, based at Kashiwadai Depot and formed as follows.
Car 2 has two single-arm pantographs, and cars 4 and 8 each have one.
Cars 1 and 10 have wheelchair spaces. Cars 4 and 9 are designated as mildly air-conditioned cars.
The first set was delivered from Tokyu Car Corporation (now J-TREC) in October 2008, and entered revenue-earning service from 15 June 2009.
A fifth set, 11005, was delivered in January 2013.
