The Choshi Electric Railway 1000 series (銚子電鉄1000形 Chōshi Dentetsu 1000-gata) is an electric multiple unit (EMU) train type operated by the Choshi Electric Railway in Japan since 1994. The two single cars were converted from former TRTA (now Tokyo Metro) subway 2000 series EMU cars originally built in 1959 and 1960 and were introduced from 29 August 1994 to replace the ageing 100 and 500 series EMU cars.
