The Naka-Meguro train disaster occurred in Japan on 8 March 2000. Five people were killed and 63 were injured when a derailed TRTA Hibiya Line train was sideswiped by a second train near Naka-Meguro Station.
At around 9 a.m. on 8 March 2000, the rearmost car of an eight-car TRTA Hibiya Line (now Tokyo Metro Hibiya Line) train from Kita-Senju to Kikuna derailed on the tight curve immediately before Naka-Meguro Station. The derailed car was then hit by the fifth and sixth cars of an eight-car Tobu Railway train travelling in the opposite direction from Naka-Meguro to Takenotsuka.
It is generally the case that if the distance between tracks is less than the width of the carriages this only allows about 600 mm clearance, so that if a train derails on the same side as the other track, it will almost certainly obstruct the other track, making a collision inevitable. Track circuits detect the presence of a train via electric current passed through the rails, which is shorted by a train car's axle or a physical break in the rails. If a derailment on an adjacent track, that doesn't cause a physical break in the other track, won't cause the track circuit to 'short' resulting in a stop signal. In this situation, a train crew member must either warn railway signal staff of the derailment, stop other trains using a handheld signal, such as a red flag, or manually short the track circuit using a specialized equipment, such as a track circuit operating clip.
A railroad switch (AE), turnout, or [set of] points (CE) is a mechanical installation enabling railway trains to be guided from one track to another, such as at a railway junction or where a spur or siding branches off.
The Tokyo Metro is a major rapid transit system in Tokyo, Japan, operated by the Tokyo Metro Co. With an average daily ridership of 6.84 million passengers, the Tokyo Metro is the larger of the two subway operators in the city; the other being the Toei Subway, with 2.85 million average daily rides.
The Tōyoko Line is a major railway line connecting Tokyo (Shibuya) to Yokohama. The line is owned and operated by the private railway operator Tokyu Corporation. The name of the line, Tōyoko (東横), is a combination of the first characters of Tōkyō (東京) and Yokohama (横浜), and is the mainline of the Tokyu network. The section between Den-en-chofu and Hiyoshi Station is a quadruple track corridor with the Tōkyū Meguro Line.
The Tokyo Metro Hibiya Line is a subway line in Tokyo, Japan, owned and operated by Tokyo Metro. The line was named after the Hibiya area in Chiyoda's Yurakucho district, under which it passes. On maps, diagrams and signboards, the line is shown using the color silver, and its stations are given numbers using the letter "H".
The Tokyo Metro Marunouchi Line is a subway line in Tokyo, Japan, operated by Tokyo Metro. The line runs in a U-shape between Ogikubo Station in Suginami and Ikebukuro Station in Toshima, with a branch line between Nakano-Sakaue Station and Hōnanchō Station. The official name is Line 4 Marunouchi Line.
In rail transport, a derailment occurs when a rail vehicle such as a train comes off its rails. Although many derailments are minor, all result in temporary disruption of the proper operation of the railway system and they are a potentially serious hazard.
On September 22, 1993, an Amtrak train derailed on the CSX Transportation Big Bayou Canot Bridge near Mobile, Alabama, United States. It was caused by displacement of a span and deformation of the rails when a tow of heavy barges collided with the rail bridge eight minutes earlier. Forty-seven people were killed and 103 more were injured. To date, it is the deadliest train wreck in both Amtrak's history and Alabama's railway history. It is also the worst rail disaster in the United States since the 1958 Newark Bay rail accident, in which 48 people died.
A track circuit is an electrical device used to prove the absence of a train on rail tracks to signallers and control relevant signals. An alternative to track circuits are axle counters.
Catch points and trap points are types of points which act as railway safety devices. Both work by guiding railway carriages and trucks from a dangerous route onto a separate, safer track. Catch points are used to derail vehicles which are out of control on steep slopes. Trap points are used to protect main railway lines from unauthorised vehicles moving onto them from sidings or branch lines. Either of these track arrangements may lead the vehicles into a sand drag or safety siding, track arrangements which are used to safely stop them after they have left the main tracks.
The Toei Mita Line is a subway line of the Tokyo Metropolitan Bureau of Transportation (Toei) network in Tokyo, Japan. The line runs between Nishi-Takashimadaira in Itabashi and Meguro in Shinagawa. Trains continue with direct service into the Meguro Line of Tokyu Corporation for Hiyoshi. The portion between Shirokane-Takanawa and Meguro is shared with the Tokyo Metro Namboku Line.
Naka-meguro Station is a railway station in Meguro, Tokyo, Japan, jointly operated by Tokyu Corporation and Tokyo Metro. Despite its name, the station is not located in Nakameguro, but in the neighboring Kamimeguro district.
The Tobu Nikko Line is a 94.5-kilometre (58.7 mi) railway line in Japan operated by the private railway company Tobu Railway. It branches from Tōbu Dōbutsu Kōen Station in Miyashiro, Saitama on the Skytree Line, extending north to Tōbu Nikkō Station in Nikkō, Tochigi.
Higashi-ginza Station is a subway station on the Asakusa Line, operated by the Tokyo Metropolitan Bureau of Transportation (Toei), and on the Hibiya Line operated by Tokyo Metro. The Hibiya Line station is subtitled "Kabukiza-mae". The station is located in Ginza, Chūō, Tokyo, Japan. Its numbers are A-11 and H-10.
Ningyocho Station is a subway station on the Hibiya Line and the Asakusa Line. It is located in the Ningyocho neighborhood of Nihonbashi, Chūō, Tokyo, Japan.
A track circuit interrupter may be fitted at catch points, trap points or buffer stops to maintain a track circuit in the 'occupied' state in the event of a derailment. The track circuit remains de-energised until the interrupter is replaced.
Kodemmachō Station is a subway station on the Hibiya Line. It is located in the Kodenmachō neighborhood of Nihonbashi, Chūō, Tokyo, Japan. Its number is H-15.
Naka-okachimachi Station is a subway station on the Hibiya Line in Taitō, Tokyo, Japan, operated by the Tokyo subway operator Tokyo Metro.
The Tobu Skytree Line is a section of the Tobu Isesaki Line operated by the private railway company Tobu Railway, extending from Asakusa Station in Tokyo to Tōbu-Dōbutsu-Kōen Station in Saitama Prefecture. Some trains from the line continue to the Tokyo Metro Hibiya Line and Tokyo Metro Hanzōmon Line. This section was branded the Tobu Skytree Line on 17 March 2012 in conjunction with the opening of the Tokyo Skytree Tower. However, in through services with the Hibiya line, the Tobu SkyTree Line actually does not stop anywhere near the Tokyo SkyTree.
