Nishitetsu Kaizuka Line

The Kaizuka Line (貝塚線) is an 11.0 km Japanese railway line in Fukuoka prefecture, run by the private railway operator Nishitetsu. It links Kaizuka Station in Higashi-ku, Fukuoka with Nishitetsu Shingū Station in Shingū. It connects to the Kashii Line of JR Kyushu at Wajiro, and the Hakozaki Line of Fukuoka City Subway at Kaizuka.

The line was 20.9 km long until Nishitetsu closed the 9.9 km section between Nishitetsu Shingū and Tsuyazaki stations on April 1, 2007. Until then, the line was called Miyajidake Line (宮地岳線).

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.
