History
The Nagoya Electric Railway (later Meitetsu) opened the Biwajima to Iwakura section, as an interurban electrified at 600 V DC, in 1910. The line was extended to Inuyama in 1912 built with double tracks. In 1922, the Biwajima to Iwakura section was double-tracked, and in 1926, the line was extended as dual track to Shin-Unuma, including a combined rail and road bridge over the river Kiso.
In 1948, the voltage was increased to 1,500 V DC, and in 1993 through services commenced on the Nagoya Municipal Subway Tsurumai Line. The road utilising the Kisogawa rail bridge was diverted onto its own bridge in 2000, ending the last such combined bridge usage in Japan.
