The Keikyū 2100 series (京急2100形) is an express-purpose electric multiple unit which operates on the Keihin Electric Express Railway. It is the successor to the 2000 series. A total of 10 trainsets with 8 cars each were built by Kawasaki Heavy Industries[1] and Tokyu Car Corp[2], and it was first put into service on 28 March 1998.
The rolling stock was designated as "2100" to commemorate the 100th anniversary of the Keihin Electric Express intended for use on its limited express services, unlike its most other rolling stock that are serving 'urban' services. The interior consisted of 'transverse' seating manufactured in Europe and was made more luxurious. Each carriage consists of only four doors, and foldable seats are installed next to each door. The windows on the 2100 series were double-glazed, with curtains installed on every window. It has a design speed of 130 km/h, though it operates only to maximum of 120 km/h in actual service.
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. Trainset 2157 carried the livery of "KEIKYU BLUE SKY TRAIN", and was put into airport services from 11 June 2005.
Its GTO-VVVF propulsion system was supplied by Siemens.[3] 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).[4] 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.[4]
