Fukuoka Subway 1000 series
The  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). 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  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. Formation
, the fleet consists of 18 six-car sets formed as follows, with four motored ("M") cars and two non-powered driving trailer ("Tc") cars. Cars 3 and 5 are each fitted with two cross-arm type pantographs. Interior
The longitudinal seats are covered with a red moquette and some parts of the saloons feature woodgrain panelling. In 1982, wheelchair spaces were added to the cars. All cars are air-conditioned. History
