Senseki Line
The is a railway line in Miyagi Prefecture, Japan, owned and operated by the East Japan Railway Company (JR East). It connects Aoba-dōri Station in Sendai to Ishinomaki Station in Ishinomaki, and provides access to the central coast areas of Miyagi Prefecture, significantly the Matsushima area. It connects with the Sendai Subway Nanboku Line at Aoba-dōri Station; the Tōhoku Shinkansen, the Tōhoku Main Line and the Senzan Line at Sendai Station; and the Ishinomaki Line in Ishinomaki. The name Senseki (仙石) comes from the combination of the first ''kanji'' of Sendai (仙台) and Ishinomaki (石巻), the two cities that the Senseki Line connects. It is also the only line in Sendai area that is powered by DC overhead power line.

JR East
The is a major passenger railway company in Japan and is the largest of the seven Japan Railways Group companies. The company name is officially abbreviated as JR-EAST or JR East in English, and as in Japanese. The company's headquarters are in Yoyogi, Shibuya, Tokyo, and next to the Shinjuku Station. It is listed in the Tokyo Stock Exchange (it formerly had secondary listings in the Nagoya and Osaka stock exchanges), is a constituent of the TOPIX Large70 index, and is also one of the three only Japan Railways Group constituents of the Nikkei 225 index, the other being JR Central and JR West. History JR East was incorporated on 1 April 1987 after being spun off from the government-run Japanese National Railways (JNR). The spin-off was nominally "privatization", as the company was actually a wholly owned subsidiary of the government-owned JNR Settlement Corporation for several years, and was not completely sold to the public until 2002. Following the breakup, JR East ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Centralized Traffic Control
Centralized traffic control (CTC) is a form of railway signalling that originated in North America. CTC consolidates train routing decisions that were previously carried out by local signal operators or the train crews themselves. The system consists of a centralized train dispatcher's office that controls railroad interlockings and traffic flows in portions of the rail system designated as CTC territory. One hallmark of CTC is a control panel with a graphical depiction of the railroad. On this panel, the dispatcher can keep track of trains' locations across the territory that the dispatcher controls. Larger railroads may have multiple dispatcher's offices and even multiple dispatchers for each operating division. These offices are usually located near the busiest yards or stations, and their operational qualities can be compared to air traffic towers. Background Key to the concept of CTC is the notion of ''traffic control'' as it applies to railroads. Trains moving in opposite ...

Automatic Train Stop
Automatic train stop or ATS is a system on a train that automatically stops a train if certain situations occur (unresponsive train operator, earthquake, disconnected rail, train running over a stop signal, etc.) to prevent accidents. In some scenarios it functions as a type of dead man's switch. Automatic train stop differs from the concept of Automatic Train Control in that ATS usually does not feature an onboard speed control mechanism. Overview Mechanical systems The invention of the fail-safe railway air brake provided an external means for stopping a train via a physical object opening a valve on the brake line to the atmosphere. Eventually known as ''train stops'' or ''trip stops'', the first mechanical ATS system was installed in France in 1878 with some railroads in Russia following suit using a similar system in 1880. In 1901 Union Switch and Signal Company developed the first North American automatic train stop system for the Boston Elevated Railway. This system was so ...

European Train Control System
The European Train Control System (ETCS) is the signalling and control component of the European Rail Traffic Management System (ERTMS). It is a replacement for legacy train protection systems and designed to replace the many incompatible safety systems currently used by European railways. The standard was also adopted outside Europe and is an option for worldwide application. In technical terms it is a type of positive train control (PTC). ETCS is implemented with standard trackside equipment and unified controlling equipment within the train cab. In its advanced form, all lineside information is passed to the driver wirelessly inside the cab, removing the need for lineside signals watched by the driver. This will give the foundation for a later to be defined automatic train operation. Trackside equipment aims to exchange information with the vehicle for safely supervising train circulation. The information exchanged between track and trains can be either continuous or int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ATACS
Advanced Train Administration and Communications System (ATACS) is an Automatic Train Control (ATC) system first introduced by JR East on the Senseki Line in 2011. It uses radio communication rather than traditional signals, and works as a moving block system. Technical description Radio transmission Communication between the train and the trackside equipment happens entirely through bidirectional radio communication. Radio base stations are placed at intervals of 2 to 3km and operates on four different frequency bands, used alternately to prevent inference. Radios operate in the 400MHz frequency band, with data transmitted using TDMA access method with Reed–Solomon error correction at 9.6kbps. The radio system are based on proprietary standards with encryption. Ground equipment Ground controller The ground controller, being the main control unit of ground equipment, is responsible for the identification of train locations based on information received from the tra ...

Railway Signalling
Railway signalling (), also called railroad signaling (), is a system used to control the movement of railway traffic. Trains move on fixed rails, making them uniquely susceptible to collision. This susceptibility is exacerbated by the enormous weight and inertia of a train, which makes it difficult to quickly stop when encountering an obstacle. In the UK, the Regulation of Railways Act 1889 introduced a series of requirements on matters such as the implementation of interlocked block signalling and other safety measures as a direct result of the Armagh rail disaster in that year. Most forms of train control involve movement authority being passed from those responsible for each section of a rail network (e.g. a signalman or stationmaster) to the train crew. The set of rules and the physical equipment used to accomplish this determine what is known as the ''method of working'' (UK), ''method of operation'' (US) or ''safeworking'' (Aus.). Not all these methods require the use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Direct Current
Direct current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A term formerly used for this type of current was galvanic current. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or ''voltage''. Direct current may be converted from an alternating current supply by use of a rectifier, which contains electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be converted into alternating current via an inverter. Direct current has many uses, from the charging of batteries to large power sup ...

Japan Freight Railway Company
, or , is one of the seven constituent companies of Japan Railways Group (JR Group). It provides transportation of cargo nationwide throughout Japan. Its headquarters are in Shibuya, Tokyo near Shinjuku Station. The Japan Railways Group was founded on 1 April 1987, when Japanese National Railways (JNR) was privatized. Japanese National Railways was divided into six regional passenger rail companies and a single freight railway company, Japan Freight Railway Company. The company has only about of track of its own, and therefore operates on track owned by the six JR passenger railways as well as other companies which provide rail transport in Japan. Economics In 2017, only about 5% of all freight in Japan is carried by rail but nearly all of that, 99%, is carried by JR Freight. Trucks carry about 50% and ships about 44%. JR Freight has seen its share of the freight market gradually decrease since 1993. In the 2010s JR Freight has been carrying more freight because of the dec ...
