China Invested $88 billion in High Speed Rail in 2009 - HSR | Clean Fleet Report - 1 views

  • China’s Ministry of Railways spent $88 billion on HSR projects in 2009 – part of an existing $300 billion plan to expand and connect all of the country’s major cities with a projected 10,000 miles of dedicated HSR lines by 2020.

Amtrak - Defining Energy Efficiency - 0 views

    Rail travel is more energy efficient, and uses less fuel, than cars or airplanes. According to U.S. Department of Energy data, Amtrak is almost 20 percent more efficient than domestic airline travel and 30 percent more efficient than auto travel ...

      This may be useful, but the emissions for trains are already low per passenger. It is just icing. We need to be investing in carbon capture and make all stations ready for the tech when it arrives.

Railway Gazette: UltraCaps win out in energy storage - 0 views

    REGENERATIVE BRAKING is widely practised, but there have to be other trains around to absorb the surplus power being fed back into the catenary or third rail. Processing the output from trains and pushing it back into the local grid is possible with an AC power supply, but very expensive with DC traction. Too often, power produced by traction motors in braking mode ends up heating resistor banks. The elegant alternative is to store the braking energy on the train. This not only avoids the electrical complications of regenerating through the traction power supply network. It reduces the rated power requirement of that network by lopping demand peaks during acceleration, saves energy by reducing losses in the catenary or conductor rail, and by limiting voltage drop it allows substations to be further apart. NiMH batteries have the necessary energy storage density in terms of kWh/kg, and are slightly more expensive, but their life in terms of charge/discharge cycles in no way matches the LRV requirement for 2million cycles over 10 years. Flywheels have been tried but never caught on for several reasons.

Maglev, diesel-electric trains vie for support in US desert - Engadget - 0 views

  • Although the mention of a magnetically levitating train outside of US borders won't grab too much attention, saying that phrase here most definitely perks up ears.

Nightclub Illuminated With 100% LED Light : MetaEfficient - 0 views

  • The Barcode nightclub was built in a disused brick Victorian railway arch in Vauxhall, south London. The entire nightclub is illuminated using only LED lights, and the sound system is also energy efficient. The architect, Woods Bagot claims that the system consumes “less electricity than the power used to boil a kettle”. If they could just give a watts per hour figure I’d be happier! Still, this is a interesting example of all-LED lighting in a building, which I’m sure we’ll see more in the coming years. Because the LEDs give off very little heat, much less AC is required to cool the building in summer. See more pictures over the fold.

Clean Break :: Ontario, Bombardier in talks for hydrogen commuter train - 0 views

  • A European consortium called The Hydrogen Train concluded a feasibility study last year that looked at demonstrating the first hydrogen-powered train in Europe on a Danish railway. The goal of the project is to launch the first train by 2010

South Africa electrical equipment for locomotives - 0 views

  • Toshiba’s track record of supplying electrical equipment for locomotives in South Africa, combined with the reputation for energy-efficient performance and reliability secured by the equipment and systems Toshiba has previously delivered, contributed to the award of the new order
Hans De Keulenaer Can a freight train really move a ton of freight 436 miles on a gallon o... - 0 views

  • This question is generated by an advertising campaign by the railroad industry, which is arguing that a good way to reduce greenhouse gas emissions is to move more freight by rail rather than by truck. An example of the industry's ads can be seen on the Web site
