Sagami Line
In April 1943, Sagami Railway took over Jinchu Railway and named two lines "Sagami Line" (original section) and "Jinchu line" (acquired section). However, in June 1944, the Sagami Line and Nishi-Samukawa branch line were purchased by the government to use the bypass between Tokaido main line and Chuo main line. At the same time, Imperial Japanese Navy Atsugi Airport was opened, so the number of passengers and amount of freight increased sharply. As a result, Sagami Railway released all management and delegated it to Tokyu. Under Tokyu, the line gained electrification to increase the carrying capacity and in 1944, all passenger lines were electrified.
