The Kurobe Senyō Railway (黒部専用鉄道 Kurobe Sen'yō Tetsudō, "Kurobe Industrial Railway") is a Japanese, 762 mm (2 ft 6 in) narrow gauge industrial railway line in Toyama Prefecture, operated by Kansai Electric Power Company. There are two lines, namely Jōbu Track (上部軌道 Jōbu Kidō) and Kuronagi Branch Line (黒薙支線 Kuronagi Shisen). The two lines go to hydroelectric power plants of Kurobe River. These lines are basically not open to public. This article is mainly about Jōbu Track.
Jōbu Track runs from Keyakidaira-Jōbu to Kurobegawa No.4 Power Station-mae, and is a part of Kurobe Route, an industrial transportation route between Keyakidaira and Kurobe dam. From Keyakidaira, Kurobe Gorge Railway Main Line runs to Unazuki neighbouring Unazukionsen of Toyama Chihō Railway Main Line. As a counterpart the tunnels are divided into 42 parts by the Jōbu Track (literally meaning "Upper Track"), Kurobe Gorge Railway Main Line is sometimes called Kabu Track (下部軌道 Kabu Kidō, "Lower Track").
The section between Keyakidaira and Sennindani was built in 1941 for the construction of Kurobegawa No.3 Power Station. The section between Sennindani and Kurobegawa No.4 Power Station-mae was built in 1963, for the construction of the said power station.
