History
The Hakata Bay Railway opened the gauge Shinhakata to Wajiro line in 1924, and extended the line to Miyajidake the following year. The line was electrified at 1,500 V DC in 1929. The company merged with the Nishi-Nippon Railway in 1942. The 1 km section from Miyajidake to Tsuyazaki opened in 1951, and in 1954 the line was re-gauged to and connected to the Fukuoka line.
The line was grade separated over the JR
Kashii Line at Wajiro Station in 1966, and CTC signalling was commissioned in 1978.
In 1986, the Shinhakata to Kaizuka section was closed and replaced by the Fukuoka City Subway
Hakozaki Line.
In 2007, the 10 km Nishitetsu Shingū to Tsuyazaki section closed due to declining patronage.
