The system integrates equipment mounted on trains with ground-based equipment using wireless communication to collect position information from the train and sent back control signal. This significantly reduces the amount of equipment and facilitate roadside benefits such as high traffic density and the use of a single drive or train without a driver. Another advantage of this system is its use of general purpose 2.4 GHz band, which makes it suitable for different countries and regions. The system has also made strong enough to avoid interference from other wireless users and allow its use in mission-critical situations. For example, Hitachi was selected CBTC system for Chongqing Monorail 3 in China, which started operations in September 2011 (operational in 17km of the 55.6km line), and the installation is being planned. Hitachi draws on this experience to accelerate global business activities in the sector of the railway system. Finally, CBTC allows the operator to efficiently control train acceleration and deceleration to maximize energy …show more content…
Basically, the control unit generates ATP ATP board speed control pattern to the next stop block based land information (stop blocks and G / R signal) received from the roadside logical unit transceiver ATP through ATP. Brake control is then activated by the speed of the train is detected by the techno-pulse generator and sensor. Some of the pattern generated by the speed limit control system is weak brake ATP pattern, the pattern of service breaks, or twist the emergency brake and if any of these patterns is exceeded, the brake command signals to apply the brakes as appropriate for each pattern. Speed train on the system board is controlled by ATP, but trains can also be operated manually between stations at speeds below the speed control pattern is determined by the ATP. In case of emergency, onboard ATP system emergency stop receiving messages via train radio equipment, and issued an order that trips the emergency brake brakes and bring the train
This essay will encounter The Long Island Rail Road first years making. The rail road was developed because the rail roads planners wanted to expand a way to get to Boston. In order for this view to happen, the service needed to make rail-road through Long Island, so they made the LIRR with the help of legislature supplying the money with 1,500,000$. This caused for New York or Brooklyn to be linked to Boston. Even though the money was good start for making the rail road, it was still very difficult to make so they to find ways to make it more efficient.
After America acquired the West, the need for efficient transportation heightened. Ideas circulated about a railroad that would spread across the continent from East to West. Republican congresses ruled for the federal funding of railroad construction, however, all actions were halted for a few years on account of a war. Following the American Civil War of 1861-1865, the race to build transcontinental railroad began in 1866. Lincoln approved Pacific Railway Act of 1862, granting two railroad companies the right to build the first American transcontinental railroad, (Clark 432).
Jay Scott Traylor was driving on a highway in North Carolina when his car struck a guardrail that was fitted with an ET-Plus end terminal. The terminal, manufactured by Trinity Highway Products, LLC, comprised three main components—an impact plate, guide channels, and an extruder head. When attached to the end of a standard guardrail, the unit was designed to absorb and dissipate crash forces by permitting the guardrail to be extruded through the unit’s head and flattened out into a ribbon. .

The New York City Subway is one of the oldest public transit systems in the world, and Manhattan has its fair share of it, especially in the form of abandoned subway stations.Subways are great mean of transportation, with great historical and geographical value. Interborough Rapid Transit company built the first subway in 1904. The subway consisted of what is today the IRT Lexington Avenue Line south of 42nd Street, the 42nd Street Shuttle and the IRT Broadway - Seventh Avenue Line between 42nd and 145th Streets. 28th Street is a part of the first IRT line of NewYork city. It a local station on the Lexington Avenue Line of the New York City Subway, located at the intersection of Park
The railroad industry is a mature market. The best option for growth is through mergers and acquisitions. By merging with Conrail, CSX would claim almost 70% of the Eastern market. By combining the rail networks CSX-Conrail would be able to offer long-haul routes between the Southern, Northeast, and Midwest ports. The combined entity would be able to consolidate overlapping operations which would reduce costs by an estimated $370 million by 2000. The cost savings would also be passed onto customers using the shorter routes between the Midwest and the South. By offering more competitive pricing an additional $180 million in operating income is expected through revenue increases. Part of this additional revenue is expected to be taken from Norfolk Southern.
The Underground Railroad despite occurring centuries ago continues to be an “enduring and popular thread in the fabric of America’s national historical memory” as Bright puts it. Throughout history, thousands of slaves managed to escape the clutches of slavery by using a system meant to liberate. In Colson Whitehead’s novel, The Underground Railroad, he manages to blend slave narrative and history creating a book that goes beyond literary or historical fiction. Whitehead based his book off a question, “what if the Underground Railroad was a real railroad?” The story follows two runaway slaves, Cora and Caesar, who are pursued by the relentless slave catcher Ridgeway. Their journey on the railroad takes them to new and unfamiliar locations,

Konkan Railway Corporation (KRC) is related to the Indian Railways (IR). It operates the Konkan Railways, a related zone of the Indian Railways. It is headquartered at CBD Belapur in Navi Mumbai. The company started its full operations of trains on 26 January 1998.The first passenger train which ran on Konkan railway tracks on 20 March 1993 between Udupi and Mangalore. Konkan Railway Corporation is at the leading position of research and development of new technologies and concepts for Indian railways. During its beginning years of operations in the mountainous Konkan region, a spate of accidents prompted Konkan Railway to investigate new technologies. The anti-collision devices, the Sky Bus and RORO are a few of the innovations from Konkan Railways.
When the driver applies the brake, the stroke sensor detects the operation of the brake and the EDIB calculates the braking force required and sends the signal to Vehicle Control Module (VCM) via control signals. The VCM in turn determines the regenerative braking force required and sends it to EDIB unit through control signals. Also, the traction motor acts as a generator to produce the regenerative braking. The EDIB now calculates the hydraulic braking force required based on the outputs from the VCM. Thus based on this calculated hydraulic braking force the motor inside the EDIB is activated to push the master cylinder piston and adjust the fluid pressure inside the master cylinder so that it matches with the target fluid pressure. The motor engages the piston and amplifies the friction brake's pressure (hydraulic pressure). Through optimum control of the friction brake's hydraulic pressure, the energy regeneration outcome is

Railway transport has proven to have several advantages over other means of passenger or goods transportation. The most significant of them all is safety; railway related injuries and deaths are statistically far less than other modes of transportation. Nowadays trains consist of several different lengths hence serving well to the cause of transporting huge number of passengers and far greater volumes of goods compared to any other means. There is a battle between developed countries to achieve high speeds which have made train journeys much quicker without influencing the ride comfort. Railways ar...
Magnetic Levitation Trains - these are high-speed trains that have powerful electromagnets to lift, guide and move them. The electromagnets lift the train to a few millimeters above the tracks. This greatly reduces friction, which is one of the main hindrances to achieving speed in any kind of transportation.
