Tōbu Keishi Line

The Tōbu Keishi Line (東武啓志線, Tōbu Keishi-sen) was a 6.3 km freight railway line operated by Tobu Railway, which ran from Kami-Itabashi Station on the Tōbu Tōjō Line, initially to a Japanese Army arsenal depot. Following the arrival of USAF forces, the area was converted to the Grant Heights USAF housing complex (present-day Hikarigaoka in Tokyo, Japan).

The line opened in 1943 as a freight-only line, and following the opening of the USAF housing complex, a passenger service was introduced in December 1947, with through services operated to and from the Tojo Line terminus at Ikebukuro, but ceased in February 1948. The line closed on 22 July 1959.
