The Keikyu N1000 series (京急新1000形, Keikyū Shin-1000-gata) is a DC electric multiple unit (EMU) train type operated by the private railway operator Keikyu on commuter services in the Tokyo area of Japan since 2002.[2][3]

Operations[edit]

The eight-car sets are primarily used on limited-stop "Rapid Limited Express" and "Limited Express" services on the Keikyu Main Line, including through-running services to the Toei Asakusa Line as well as the Keisei Oshiage Line, Keisei Main Line, and Hokuso Line.[3] Some of these eight-car sets are also being used on the Keikyu Airport Line. Four-car sets are commonly used to form 12-car "Rapid Limited Express" and "Limited Express" services, and are also used singly on all-stations "Local" services;[3] in addition, some are used on the Keikyu Daishi Line,[4] with some being used to form eight-car trains for use on inter-running services to the Asakusa Line and Keisei lines.[5] The six-car formations delivered from 2011 are generally used on all-stations "Local" services.[3] The N1000 series sets can be used in multiple with other Keikyu EMU types, including the 600 series, 1500 series, 2000 series, and 2100 series.[3]

Variants[edit]

Since the first set was introduced in 2002, the type has undergone a number of design improvements. Sets built from 2002 to 2006 have painted aluminium bodies, whereas sets built from 2007 onward (sets 1073 onward) have stainless steel bodies. More detailed variations are described below. The Siemens inverters fitted to the first two batches prior to their refurbishment between 2017 and 2021 were known in Japan by the nickname "Do-re-mi-fa Inverter" (ドレミファインバータ), due to the distinctive ascending musical scale the trains produced when accelerating from a standstill.[6]

Batch 1[edit]

Delivered February to June 2002.

  • 8-car sets x 3: 1001, 1009, 1017

1000-1890 series set 1891 in May 2021

The 1000-1890 series 4-car sets were introduced into service from 6 May 2021 as part of Batch 20.[22] These are the first trains in the fleet to feature rotating banks of seats; they can be arranged in a longitudinal or transverse seating configuration when required. The seats are similar to those used on the 2100 series but are 10 mm (0.39 in) wider.[23] Power sockets are also provided. They are also the first trainsets in the fleet to feature toilets; car 2 features a universal-access Western toilet,[23] and car 3 features a men's toilet.[24] The trains are intended for use on reserved seat "Wing" services as well as chartered event services.[25]

Shortly after their initial entry into service, Keikyu announced that it would procure three additional 4-car sets as part of its investment plan for fiscal 2021.[26] The first of these three sets (1893) entered service on 29 November 2021 as part of Batch 21.[27][better source needed]

Following a nickname contest for the 1000-1890 series fleet held between June and July 2021, the nickname "Le Ciel" (The Sky in French) was announced for the 1000-1890 series fleet on 24 December.[28] Four entries were given honourable mentions: "Red Rabbit", "Leap", "Sunsun", and "Kofu".[29] From 26 March 2022, the intermediate cars of sets 1891, 1892, 1894, and 1895 were adorned with "Le Ciel" branding.[30]

On 26 May 2022, the 1000-1890 series received the Blue Ribbon Award.[31]

Yellow Happy Train[edit]

8-car set 1057 was repainted into a special "Yellow Happy Train" livery from May 2014, for the collaboration with the private railway operator Seibu Railway. In return, Seibu repainted one of its 9000 series trainsets into Keikyu livery, known as the "Seibu Red Lucky Train".[44] The "Yellow Happy Train" livery was originally intended to be used for about three years; however, due to its popularity, on 27 April 2017, Keikyu announced its decision to keep the livery and to also repaint the passenger doors yellow from their original silver colour.[45]
