The Keikyu 2100 series (京急2100形?) is a DC electric multiple unit (EMU) train type operated by the private railway operator Keikyu in the Tokyo area of Japan since 1998. It replaced the earlier 2000 series on limited-stop Rapid Limited Express (快特 Kaitoku?) services.[1] A total of 10 8-car sets were built by Kawasaki Heavy Industries,[2] and Tokyu Car,[3] and the first sets entered service on 28 March 1998.

Electrical systems[edit]

Its GTO-VVVF propulsion system was supplied by Siemens.[4] The ability to produce a "fa-so-la-ti-do-re-mi-fa-so" scale when the propulsion starts up quickly became a signature to the 2100 series when it was introduced, earning the nickname as the "singing train" (歌う電車?).[5] Subsequently, similar propulsion was also installed on 56 cars of the N1000 series. The uniqueness of the propulsion system made its way into various music and popular culture, such as Super Bell"Z. However, it was reportedly expected that this feature may soon disappear, as substitute parts are no longer available when the propulsion system is due for replacement in a decade or earlier.[5]

Formation[edit]

As of 1 April 2012, 10 8-car sets were in operation, formed as follows, with four motored (M) cars and four trailer (T) cars, and car 1 at the Misakiguchi end.[6]

Car No. 1 2 3 4 5 6 7 8
Designation Muc T Tp Mu Ms T Tp Msc
Numbering 2100 2100 2100 2100 2100 2100 2100 2100

The two "Tp" cars are each fitted with two single-arm pantographs.[6]

Interior[edit]

Passenger accommodation consists of transverse seating arranged 2+2 abreast, with seat backs that can be flipped over to face the direction of travel. The windows on the 2100 series are double-glazed, with curtains.

TV screens have been installed on a select few cars 2109 and 2133 as part of an experimental program, broadcasting NHK and other assorted advertisements.[citation needed]

Livery variations[edit]

Trainset 2157 carried a "Keikyu Blue Sky Train" livery, and was put into airport services from 11 June 2005.

Refurbishment[edit]

Set 2101 was the first 2100 series set to undergo refurbishment, in 2013. Modifications include replacing the passenger windows at the ends of each car with opening windows, replacing the curtains on these windows with roller blinds, and replacing the original fluorescent tube lighting with LED lighting.[7]
