Hybrid cars, trucks and buses have already hit the road. Now, make way for the Green Goat, the world’s biggest hybrid. It’s a 2,000-horsepower locomotive that radically reduces fuel consumption and emissions of pollutants.
The Green Goat is a diesel-electric hybrid in which the normal massive diesel locomotive engine is replaced by a 290-horsepower inline 6-cylinder diesel truck engine and a 600-volt battery bank. The batteries supply the power needed to drive the electric traction motors on the wheels of this 280,000-pound “goat.”
Goat is railroad lingo for the smaller locomotives used for moving rail cars around over short distances.
… could this “hybrid diesel electric” technology be used for cheaper LRT system in Klang Valley?
- RailPower Technologies Corp – developer of the Green Goat.
- Train Scan October 2001 – news of RailPower Technologies demo Green Goat, including pictures and diagram.
- First prototype of a hybrid diesel-electric rail car – May 2003 article about East Japan Railway Company’s NE Train. “The diesel engine drives the generator, and the generator supplies electricity to the electric motors that drive the ! wheels. In the future, this system can be adapted to a fuel cell system by simply replacing the engine and the generator with fuel cell stacks.”
- TriMet Hybrid Diesel-Electric Buses – manufactured by New Flyer of America. “Its diesel engine powers an electrical generator which charges a battery pack on the roof. The batteries then power an electric motor that turns the wheels. (The diesel engine also powers the air conditioning.) When the bus slows down during braking, it sends extra energy to further charge the batteries.”
- Low cost, hybrid diesel/electric ultra-light rail Minitram – manufactured by Green Motorsport Limited UK, pre production mid 2004. “The Kalamata ULR system will comprise a 5km route of conventional metre-gauge tramway track, a depot, 23 stops and eight hybrid diesel electric trams, each with 45-passenger capacity. It is expected that with the associated civil works, to be carried out by a local contractor, the total project cost will amount to around EUR 8 million (Â£5 million). This represents only 10% of the cost of building a conventional light rail system.”
