The Choshi Electric Railway 1000 series (銚子電鉄1000形, Chōshi Dentetsu 1000-gata) is an electric multiple unit (EMU) train type formerly operated by the private railway operator Choshi Electric Railway in Chiba Prefecture, Japan, from 1994 until 2016. The type originally consisted of two single cars, DeHa 1001 and DeHa 1002, converted from former TRTA (now Tokyo Metro) subway 2000 series EMU cars, originally built in 1959 and 1960, and introduced from 29 August 1994 to replace the ageing 100 and 500 series EMU cars. Car 1002 was withdrawn in February 2015, and car 1001 was withdrawn in February 2016.
