Why high-speed rail won t help the environment?

Building high-speed rail systems require steel and concrete, the manufacturing of which typically generates greenhouse gases. Trucks, bulldozers, and other construction site equipment also consume energy. Thus, during their long construction phases, high-speed rail projects add greenhouse gases.

The results of a national survey that show that nearly two-thirds of Americans are interested in traveling by high-speed rail and the figure soars to 74 percent among those in the 18-24 age brackets.

High-speed rail lines are proposed for California, Nevada, Texas, Georgia and the Pacific Northwest, and already under construction in California's Central Valley.

High-?speed trains, in particular, were rendered obsolete in 1958, when Boeing introduced the 707 jetliner, which was twice as fast as the fastest trains today. Slower than flying, less convenient than driving, and more expensive than either one. Aside from speed, what makes high-?speed rail obsolete is its high cost.

High-speed rail is generally regarded as the pinnacle of attractive and green transportation. But all too often, it makes train travel more expensive and less flexible. In the end, costly high-speed lines may just push more people into cars.

Implementing high-speed rail will keep billions of dollars in the U.S. economy by decreasing the amount of oil that the U.S. consumes. According to the International Association of Railways (UIC), high-speed rail is eight times more energy efficient than airplanes and four times more efficient than automobile use.

High-Speed Rail is the Solution. Shifting drivers to trains creates fewer greenhouse gas emissions, since trains are far more energy efficient than cars (or planes).

Compared to flying, using the train emits on average six times less GHG emissions.

46.0 g CO2 / pkm The analysis concludes that the carbon footprint of high speed rail including operation, track construction and rolling stock construction is about 14 to 16 times less than transport by private car or airplane.

High speed trains run on electricity instead of diesel fuel. Because much of the world's electricity is still generated at fossil fuel burning power plants, high speed trains do contribute to carbon emissions, however the climate impact of one train is significantly less than that of many personal vehicles.

Trains Emit Less CO2 Than Other Transport Methods Recently developed hydrogen-powered trains are the most eco-friendly trains in the world, emitting nothing except steam as a by-product and creating very little noise.

The California HSR, for example, will remove 12 billion pounds of carbon dioxide per year by 2030 because it uses electricity generated from wind, solar, and other renewable resources. In addition, California's HSR will save 12.7 million barrels of oil by 2030.

This paper highlights that HSR can help achieve accessibility of rural area and poverty alleviation simultaneously. An understanding of the effect is critical for policymakers to promote intra-regional development, balancing efficiency and regional equality.

California's plan to link Los Angeles to San Francisco by high-speed rail is expected to cost $68 billion. Critics argue that such services cannot survive without public subsidies and that the United States has few of the dense urban areas that have made such train services successful in places like France and Japan.

MORE DETAILS

California's plan is to build an electric train that will connect Los Angeles with the Central Valley and then San Francisco in two hours and 40 minutes. But 15 years later, there is not a single mile of track laid, and executives involved say there isn't enough money to finish the project.

China initially relied on high-speed technology imported from Europe and Japan to establish its network. Global rail engineering giants such as Bombardier, Alstom and Mitsubishi were understandably keen to co-operate, given the potential size of the new market and China's ambitious plans.

He said there are only a few examples of high-speed rail networks that turn a profit, due to a rare combination of passenger numbers and distance. For example, most of the companies that run Japan's Shinkansen or bullet train lines operate at a profit, as do some fast trains on France's state-owned SNCF network.

High-speed train revolution China has built around 26,000 miles (42,000 kilometers) of dedicated high-speed railways since 2008 and plans to top 43,000 miles (70,000 kilometers) by 2035. Meanwhile, the United States has just 375 route-miles of track cleared for operation at more than 100 mph.

That works out to $200 million a mile for hilly areas. At these costs, Obama's original high-?speed rail plan would require well over $1 trillion, while the USHSR's plan would need well over $3 trillion. Building a system longer than China's would cost at least $4 trillion.
