The Sanshin Tetsudō ( Japanese 三 信 鉄 道 ) was a private railway company in Japan . After its establishment in 1927, it built and operated a 67 km long section of what would later become the Iida Line . This began in Mikawa-Kawai in Aichi Prefecture and led to Tenryūkyō in Nagano Prefecture . The name of the railway company was made up of the respective first Kanji -special the traversed historical provinces Mikawa ( 三河) and Shinano ( 信 together濃). After the line became state property in 1943, the company was liquidated seven years later.
From the 1890s, three railway companies built in several stages on the later so-called Iida line : the Toyokawa Tetsudō and its subsidiary Hōraiji Tetsudō from the south and the Ina Denki Tetsudō from the north. After three decades, the routes reached on the one hand from Toyohashi via Ōmi to Mikawa-Kawai , on the other hand from Tatsuno to Tenryūkyō . A 67 km long section was still missing between Mikawa-Kawai and Tenryūkyō. Despite the mountainous terrain and the low population density, there was a desire to connect the two branch lines. For this purpose, the three companies named jointly commissioned the surveying work , which began in April 1927.
In 1926, the electricity companies Tenryūgawa Denryoku and Tōhō Denryoku (both later merged into Chūbu Denryoku ) submitted their own competing concession applications for railway lines in the same area, with the help of which the construction of hydropower plants on Tenryū should be facilitated. The various interested parties came together and founded a new railway company called Sanshin Tetsudō on December 20, 1927, based in Tokyo . The two electricity companies each owned 25% of the share capital of ten million yen .
The construction of the line began in August 1929; To a large extent, poorly paid Korean workers were used to keep costs as low as possible. The geological conditions were difficult, as the route leads through unstable rock layers in a fault zone . There were repeated strikes by the Koreans, demanding a significant improvement in security measures and timely payment. Due to the global economic crisis , the company ran into financial difficulties and in 1931 was forced to halt construction for several months. After a change of management and the assurance of a significant loan from Mitsubishi Bank , the work could be continued. On October 30, 1932, the opening of the first section from Tenryūkyō to Kadoshima took place.
Step by step, further sections of the route were put into operation: on December 21, 1933 from Mikawa-Kawai to Tōei, on November 11, 1934 from Tōei to Chūbu-Tenryū , on November 15, 1935 from Kadoshima to Nukuta, on April 26, 1936 from Nukuta to Hiraoka, on November 10, 1936 from Chūbu-Tenryū to Tenryū-Yamamuro, on December 29, 1936 from Tenryū-Yamamuro to Ōzore and the following day from Hiraoka to Kowada. With the commissioning of the last section from Ōzore to Kowada on August 20, 1937, continuous operation could begin. The Sanshin Tetsudō took over the long-distance traffic between Toyohashi and Tatsuno; Due to different contact wire voltages, however, the locomotives had to be replaced in Tenryūkyō.
Since the construction costs were higher than originally assumed, higher prices had to be charged for freight transport, which in turn had a negative effect on the operating result. During the Pacific War , the government wanted to bring under its control several strategically important private railways that had been established after the first wave of nationalizations in 1906/07 . After the Reichstag had passed a nationalization law as requested, the Railway Ministry took possession of the Sanshin Tetsudo railway facilities on August 1, 1943 and merged them with those of the three other railway companies to form the Iida line. The company remained in existence for the time being, renamed itself Sanshin kōkūkiki and manufactured aircraft parts. It ceased production in July 1945 and then began liquidation , which lasted until 1950.
