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.[1][2]

Operations[]

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 and from the Toei Asakusa Line, Keisei Oshiage Line, Keisei Main Line, and Hokuso Line.[2]Some of these eight cars sets are also being used on the Keikyu Airport Line. Four-car sets are used to form 12-car "Rapid Limited Express" and "Limited Express" services, and are also used singly on all-stations "Local" services.[2] The six-car formations delivered from 2011 are generally used on all-stations "Local" services.[2] 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.[2]

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.
