Japan to launch first hybrid trains

July 29, 2007 - 11:59AM

Winding through rice paddies and lazily blowing its whistle along bubbly creeks, a two-car train in rural northern Japan is the latest entrant in the battle against global warming.

Following its runaway success with hybrid cars, Japan is bringing the world hybrid trains. Regular passenger runs are set to begin Tuesday on a short mountain route, the first time a diesel-electric hybrid train will be put into commercial service.

"It's part of our efforts to be green," Yasuaki Kikuchi, a spokesman for East Japan Railway Co, said Friday during an exclusive trial run for The Associated Press.

Compared to cars, trains are a relatively small contributor to global warming. In the United States, railways contribute just four per cent of transportation-related emissions of carbon dioxide, the main greenhouse gas blamed for global warming.

But the popularity of hybrid cars, such as Toyota Motor Corp's best-selling Prius, is helping to boost interest in hybrid trains. Railway companies around the world, including America's Amtrak and Germany's Deutsche Bahn AG, are working on or investigating the technology.

Cost remains a hurdle. The Japanese train, which boosts fuel efficiency by 20 per cent and reduces emissions by up to 60 per cent, runs nearly 200 million yen ($A1.95 million), twice as much as a standard train, Kikuchi said.

The Kiha E200, as it is known, is equipped with a diesel engine, two electric motors under each of its cars and lithium ion batteries on the roof.

With the word "hybrid" splashed in silver across its side, the otherwise normal-looking train rolls quietly out of Nakagomi station, powered by its four electric motors.

The diesel engine only kicks in with a rumble when needed to climb a hill or if the batteries run low.

The batteries are recharged when the train slows down. After the power is switched off, the motors continue to turn for a while, and that energy - wasted in a non-hybrid train - is used to recharge the batteries.

Besides the usual buttons and dials, the conductor also has a touch-panel monitor. Arrows show which way energy is flowing, connecting boxes that represent the engine, generator, motor and battery, busily changing direction every few minutes. Whether cars or trains, hybrids delicately balance the two sources of power, relying on a computer to minimise waste.

The Kiha E200, which seats 46 and can hold 117 passengers including people standing, is debuting on a line that runs about once an hour on a 79 kilometre route through a mountain resort area.

East Japan Railway will gather data on fuel consumption, which is expected to vary with different passenger loads; maintenance needs and whether the power holds up for heating in winter, said company engineer Mitsuyoshi Yokota.

In North America, Railpower Technologies Corp has developed a hybrid train called the Green Goat for moving freight cars in a rail yard.

But industry efforts are focused on developing cleaner fuels for non-hybrid trains, said Allen Schaeffer, executive director of the Diesel Technology Forum, a trade association representing engine and equipment manufacturers.

"Here in the US, we're not really looking at hybrid technology as replacing the main locomotive," he said.

Hybrid trains, long viewed as impracticable because it's cumbersome to get the various parts to work together, are catching on thanks to hybrid cars, said Makoto Arisawa, an ecology professor and train expert at Keio University in Tokyo.

"Maybe we can't expect too much from a railway this small," he said. "For the technology to be effective, it must become more widespread."

That didn't stop Hitomi Shimizu, 29, who runs a nearby inn, from showing up at Nakagomi station to get a snapshot of herself on the platform with the train.

"I'm so proud of being part of a community with a train that's gentle to the environment," she said.

Hybrid rail cars (rail motors) could be used to great effect on a commuter service Gatton to Rosewood.

Also provide a regular service from Toowoomba to Brisbane.  There are many places in Australia where they could be used.

Hybrid technology has reached a stage of development where it is now mainstream in automobiles.
Rail cars are an ideal development and would have much application on our networks. 

Even local commuter services in places such as Townsville and Cairns, Ballarat and Bendigo, Newcastle and Hobart.

I have a honda hybrid, it is a superb vehicle.  eg.

From  http://envirofuel.com.au/2007/09/01/honda-civic-wins-german-environmental-car-rating/

Honda?s Civic Hybrid has been named Germany?s most ecological car for the second year running by the Verkehrsclub Deutschland (VCD: a major transport and environment organisation in Germany) in its Environmental Car Ratings for 2007-2008.

According to the Envirofuel German translator the categories that made up the ratings were:

    * CO2 emissions
    * Noise
    * Carcinogens
    * Other emissions
    * Effect on nature

This is the second year running that the VCD has chosen the Civic Hybrid as its environmental winner. In 2006 the vehicle beat 350 contenders to secure the coveted first place in the VCD Environmental Car Ratings. In addition, the judges rated the Civic Hybrid as the top car in the compact class.

Retailing from $32,990, the Civic Hybrid is Australia?s most affordable hybrid vehicle. It combines a petrol engine with an electric motor to produce 85kW and 170Nm, with the ability to switch off the internal combustion engine when the car comes to a stop. These factors contribute greatly to the reduction of fuel consumption and emissions, particularly in city traffic.

The Civic Hybrid has a standard fuel consumption of 4.6 litres per 100 km (51.13 mpg) and emissions of 109 grams of CO2 per km (174.4 g/mile).

There are options.  It is just takes leadership ...
