The Fukuoka Subway 1000 series (福岡市交通局1000系) is an electric multiple unit (EMU) train type operated by the Fukuoka City Transportation Bureau on the Hakozaki Line and Kūkō Line in Fukuoka, Japan. The trains also inter-run to/from the Chikuhi Line, operated by Kyushu Railway Company (JR Kyushu).^[1]^[2]

Design

Because the train line runs near the coast, car bodies were constructed of a stainless steel skin on a conventional steel frame for corrosion resistance. The car bodies are unpainted with blue and white stripes representing the Genkai Sea. Each car is 20 m (65 ft 7 in) long with four pairs of doors per side. Early trainsets had opening windows, but these were subsequently replaced with sealed windows. The trains have emergency exit doors at the ends. The doors and window wipers were added after refurbishment.^{[verification needed]}

History

The 1000 series entered service on the Fukuoka City Subway coinciding with its opening on 26 July 1981. In 1982, it received the 22nd Laurel Prize.

Driver-only operation commenced on 20 January 1984, using automatic train control (ATC). The cabs are equipped with a master controller, brake handle, and automatic train stop (ATS) system for manual operation.^{[citation needed]}

Refurbishment

Between 1997 and 2004, 15 years after the first trains were built and after the introduction of the 2000 series, the trains underwent refurbishment. After refurbishment, the trains were called 1000N series. Refurbishment included the following major modifications.^[4]

Variable-frequency drive added
Cab end window changed (similar to 2000 series)
Large windows changed
Rollsign destination indicators replaced with LED indicators
Interior veneer panelling and floors changed
