The is a railway line that links Odawara Station in Kanagawa Prefecture and Hamamatsuchō Station in central Tōkyō, Japan. Summary The Tōkaidō Freight Line was first opened on 20 December 1914 between Shiodome Freight Terminal and Shinagawa Station, using the alignment of the first railway line ever to be built in Japan, the Tokyo-Yokohama Railway, originally opened in 1872. The Tōkaidō Freight Line runs parallel to the immediate west of the Yokosuka and Tōkaidō passenger lines from Odawara Station to Higashi-Totsuka Station, where it veers west via Yokohama Hazawa freight station and long tunnels bypassing Yokohama. Near Tsurumi Station, the bypass rejoins the main passenger route for a short distance, and has connections to the freight-only to Sakuragichō Station, the Hinkaku Line and Musashino Line. The freight line then curves east, briefly sharing tracks with the Nambu Branch Line between and stations, then veers north past Kawasaki freight station, under the entrance to Haneda Airport northward to the Tokyo Freight Terminal. The line north from here, currently dormant, continues to Hamamatsuchō Station alongside a branch of the Tōkaidō Shinkansen used to move empty rolling stock to and from a nearby depot. Beyond Hamamatsuchō Station the Tōkaidō Freight Line also continued to Shibaura Station (located on a branch line), the Shiodome Freight Terminal (the site of the original Shimbashi Station) and eventually to Tokyo Market Station (located at the Tsukiji fish market). The Tokyo Market Station closed in 1984, followed by Shibaura Station in 1985 and Shiodome Freight Terminal in 1986. The latter dormant section was closed in the 1990s to enable construction of the Toei Ōedo Line subway near Hamamatsuchō Station. Until 1980, the Tōkaidō Freight Line included the Hinkaku Line until it was converted for passenger use as part of the Yokosuka Line. Takashima Line The freight-only Takashima Line is a branch of the Tōkaidō Freight Line between Tsurumi Station and Sakuragichō Station, giving access for freight trains to and from the Negishi Line. It branches off from Tsurumi Station and ends at Sakuragichō Station in Yokohama, with a branch between Tsurumi and Sakuragichō leading off to Shinkō Station located at Pier 4 of the Port of Kawasaki.
