The Keihan Ishiyama Sakamoto Line (京阪石山坂本線, Keihan Ishiyama Sakamoto-sen) is a railway line in Shiga Prefecture, Japan, operated by the private railway operator Keihan Electric Railway.
The Otsu Railway opened the Hamaotsu to Awazu section in 1913, electrified at 600 V DC.[1] The line was extended to Ishiyamadera (as single track) the following year.[citation needed]
The Hamaotsu to Miidera section opened in 1922 (dual track electrified), and in 1927 the company merged with a tourist boat operator to become the Biwako Railway & Steamship Co., which extended the line to Sakamoto the same year.[citation needed]
Keihan acquired the company in 1929 (and divested the steamship component immediately), connecting the line to its Keishin line in 1939.[citation needed]
The Awazu to Ishiyama section was double-tracked in 1943, but in 1945 the Sakamoto to Shigasato section was singled and the rails recycled for the Japanese war effort. The dual track was reinstated in 1947.[citation needed]
The voltage was increased to 1,500 V DC in conjunction with the voltage upgrade on the Keishin line.[citation needed]
