Railpower GG20B

The Railpower GG20B Green Goat is a low-emissions diesel hybrid switcher locomotive built by Railpower Technologies Corp. It is powered by a single Caterpillar C9 I6 engine developing 300 horsepower (224 kW), which is also connected to a large battery bank where both sources combine for a total power output of 2,000 horsepower (1,490 kW). To date, there have been more than 50 GG20B diesel hybrid genset switchers manufactured since their first introduction in 2004.^[2]

Fuel Cell Testbed

BNSF Railway and Vehicle Projects converted a GG20B to an experimental testbed, for the use of hydrogen fuel cells. The new locomotive is designated HH20B. The locomotive was publicly demonstrated for the first time on June 29, 2009, at Topeka, Kansas.^[4][5]

The locomotive, BNSF 1205, was built initially for the Canadian Pacific Railway, but was not delivered, due to the cancellation of the order. It was sold to BNSF in 2008, and shipped to the railroad's shops at Topeka, Kansas for conversion. The diesel generator set was removed, and the fuel cell power unit was installed in its place. Hydrogen storage is in a set of tanks installed in a heavily vented enclosure on top of the locomotive's long hood, above the batteries.^[6]
