Executive Summary In traditional signaling system on railway application, it used the Fixed Block System (FBS) and Moving Block System (MBS) is commonly employed to control train operation on track. On this system when a leading train has stop moving it will block the behind follow as train operation. If a leading train is halt on track for any unexpected reasons for a long time. That will be a big jam-up occurs on track. For this dense queue result, the unexpected interaction situation between running trains when they begin to move again. This may cause excessive short-time overloads to occur on nearly feeder station. Which is caused it the peak electrical demand problem. The railway electrical engineer call this is "starting problem". Therefore operators in depth study how to improve the signaling system performance to reduce the electrical peak demand. (MBS) is according to the above problems creation, it include time delay & accelerate rate techniques, is identified to "Peak Demand Reduction (PDR) techniques. This project will based on PDR proposed idea and concept, through the software to simulation studies the peak demand reduction, delay and energy saving. Simulation software will collect train starting characteristic input parameter. Through different calculation and data comparison to find out an simple graph to explain comparison in terms of Peak Demand Reduction (PDR) techniques. In summary, this project forces on the study of peak power demand reduction of train operation on track for recovery of train service from disturbance. CONTENT 1. INTRODUCTION 1 2.

MATLAB is released by the U.S. MathWorks main face of scientific computing, visualization and interactive program designed high-tech computing environment. It numerical analysis, matrix computation, scientific data visualization and modeling and simulation of nonlinear dynamic systems, and many other powerful features are integrated in an easy to use Windows environment, and for scientific research, engineering design, and the need for effective numerical numerous scientific field provides a comprehensive solution. Finally, the task for the project is to find out the best solution in peak demand reduction of train operation.
(c), building up the potential-energy level. As the train enters the loop (d), it has a lot of kinetic energy and not much
The Electromagnetic Suspension (EMS) system has a large electrical power source, which is need to power the coils through the track’s guideways. Once powered, these guideways become magnetized, which repels the magnets built into the bottom of the train above it. The polarity of the magnetized coils is changed by constantly alternating the electric current supplied to the coils, which causes the magnetic field in front of the train to pull it forward.

Amtrak is a state-owned, for profit, national railroad Company that provides efficient rail service both long and short distance transportation services. Being the primary provider of passenger-rail service in the U.S has a network that connects more than 500 cities and towns in 46 states. It offers long-distance and short-distance service corridors throughout nationwide operating daily, offering several choice of service class – first class sleeping car, custom class and economic services for different age groups with different travel needs. Amtrak receives federal funds to be used for their operating expenses. Its ridership and revenue growth have progressively increased in the past five-year successfully building relationships with the public and customers, recreating branding, and improving new services/quality, and it projects a continued growth in passenger revenue at about 4% per year with modest growth in passenger ridership (Exhibit C4.1, Page 245).
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.
When the lights are flashing you are not allowed to go and stay at a complete stop until the train has passed and the lights stopped flashing. If youthink the lights are not working do not cross the tracks until you have a clear view and can clearly see that there are no trains coming. When the barriers are down it is for your ownprotection and you are not allowed to cross through the barriers. Another common thing nearand around railroad crossings are warning signs that let you know what is ahead. There canalso be X’s and letters painted on the road or curb that warn you of the crossing. There arecrossbuck signs that let you know how many tracks there are. The caution is advised will all kinds of vehicles and not just cars. School buses, motorcycles, bicycles, and trucks with hazardous materials all have to follow the same laws and should all take the crossings seriously. Trains also can come at any time and you should always be ready to stop for a train as they can cross at any time day or night. If you so happen to get stuck on the train tracks and you will not be able to get it off the tracks, you need to get out immediately and get off the
“This is an urgent warning to each and every one of you that there is a careful, deliberately planned campaign to swindle you out of your most important and valuable public utilities – your Electric Railway System.” (Span)
The emergency brake cord on all trains are the one thing that all passengers have complete control over and almost all passengers on the train know how to use them and
It is my position that implementation of autonomous trains is not only unsafe but unconscionable given the history of the railroads safety records. When left unregulated they have proven that profits and return on shareholder investment far outweigh any concerns for the safe operations of their trains. Without any humans on a train the risks are far greater to the public, especially when trains are being run heavier and longer every day. When hazardous materials (Hazmats) are put into this equation the public’s well-being is surely in serious jeopardy. It is my understanding that one of the primary responsibilities of the FRA is to ensure that public and employee safety is placed at the forefront of any policy or regulation.
For the prevantion of the electricity blackout we need to build smart power grid. A modernized electrical grid that uses analog or digital information and communications technology to gather and act on information, such as information about the behaviours of suppliers and consumers is known as a smart grid. This is used to improve the efficiency, reliability, economics, and sustainability of the production and distribution of electricity in an automated fashion[12]. The important aspects of smart grid is to electronic power conditioning and control of the production and distribution of
Abstract- Maglev trains, also known as magnetic levitation trains, are public transportation vehicles that are commonly used in Spain, China, and other parts around the world. They are mainly known for using magnetism in order to "levitate" above the tracks. Maglev trains are also known to be remotely quieter than normal trains and emit lower amounts of carbon dioxide.
Transportation system is a dynamic system. Information about traffic must be regularly updated to keep pace with ever-changing transportation system. Data must be collected and analyzed systematically to get representative information.
Increased road capacity, reduced costs. A type of train like lane management also known as platooning will reduce traffic congestion drastically and increase overall capacity of existing road networks.
