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 tomorrow 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, said on Friday during an exclusive trial run.

Compared to cars, trains are a relatively small contributor to global warming. In the US, railways contribute just 4 percent 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's best-selling Prius, is helping to boost interest in hybrid trains. Railway companies around the world, including Amtrak in the US and Germany's Deutsche Bahn, are working on or investigating the technology.
Cost remains a hurdle. The Japanese train, which boosts fuel efficiency by 20 percent and reduces emissions by up to 60 percent, runs nearly ?200 million (US$1.7 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 the 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 minimize waste.
The Kiha E200, which seats 46 and can hold 117 people including standees, is debuting on a line that runs about once an hour on a 79km 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, company engineer Mitsuyoshi Yokota said.
In North America, Railpower Technologies 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 as it's cumbersome to get 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 the station to get a snapshot of herself with the train.
"I'm so proud of being part of a community with a train that's gentle to the environment," she said.
Polish presidential candidates offered different visions of Poland and its relations with Ukraine in a televised debate ahead of next week’s run-off, which remains on a knife-edge. During a head-to-head debate lasting two hours, centrist Warsaw Mayor Rafal Trzaskowski, from Polish Prime Minister Donald Tusk’s governing pro-European coalition, faced the Eurosceptic historian Karol Nawrocki, backed by the right-wing populist Law and Justice party (PiS). The two candidates, who qualified for the second round after coming in the top two places in the first vote on Sunday last week, clashed over Poland’s relations with Ukraine, EU policy and the track records of their
Four people jailed in the landmark Hong Kong national security trial of "47 democrats" accused of conspiracy to commit subversion were freed today after more than four years behind bars, the second group to be released in a month. Among those freed was long-time political and LGBTQ activist Jimmy Sham (岑子杰), who also led one of Hong Kong’s largest pro-democracy groups, the Civil Human Rights Front, which disbanded in 2021. "Let me spend some time with my family," Sham said after arriving at his home in the Kowloon district of Jordan. "I don’t know how to plan ahead because, to me, it feels
‘A THREAT’: Guyanese President Irfan Ali called on Venezuela to follow international court rulings over the region, whose border Guyana says was ratified back in 1899 Misael Zapara said he would vote in Venezuela’s first elections yesterday for the territory of Essequibo, despite living more than 100km away from the oil-rich Guyana-administered region. Both countries lay claim to Essequibo, which makes up two-thirds of Guyana’s territory and is home to 125,000 of its 800,000 citizens. Guyana has administered the region for decades. The centuries-old dispute has intensified since ExxonMobil discovered massive offshore oil deposits a decade ago, giving Guyana the largest crude oil reserves per capita in the world. Venezuela would elect a governor, eight National Assembly deputies and regional councilors in a newly created constituency for the 160,000
North Korea has detained another official over last week’s failed launch of a warship, which damaged the naval destroyer, state media reported yesterday. Pyongyang announced “a serious accident” at Wednesday last week’s launch ceremony, which crushed sections of the bottom of the new destroyer. North Korean leader Kim Jong-un called the mishap a “criminal act caused by absolute carelessness.” Ri Hyong-son, vice department director of the Munitions Industry Department of the Party Central Committee, was summoned and detained on Sunday, the Korean Central News Agency (KCNA) reported. He was “greatly responsible for the occurrence of the serious accident,” it said. Ri is the fourth person
