Hybrid Locomotive Gains Traction

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.
