Design
edit
The 8000 series was introduced in 1986 to replace ageing rolling stock which were mostly derived from Osaka Municipal Subway rolling stock. It was also the first Kitakyū rolling stock type to feature air conditioning in the passenger interiors and driver cabs. It was also one of the three recipients of the 27th Laurel Prize of the Japan Railfan Club.[1]
