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 six cylinder inline engine developing {{convert|300|hp|lk=on|sigfig=3}}, which is also connected to a large battery bank where both sources combine for a total power output of {{convert|2000|hp|lk=on|sigfig=3}}. To date, there have been more than 50 GG20B diesel-electric hybrid switchers manufactured since their first introduction in 2004.[http://www.trainweb.org/gensets/railpower.html Railpower Genset Switchers]

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.{{cite web|title=New locomotive unveiled|url=http://cjonline.com/news/2009-06-29/new_locomotive_unveiled}}{{cite web|title=BNSF explores locomotive fuel cell|url=http://www.blet-bnsfmrl.org/index.asp?NewsStory=289|access-date=2009-07-09|archive-date=2011-10-07|archive-url=https://web.archive.org/web/20111007235203/http://www.blet-bnsfmrl.org/index.asp?NewsStory=289|url-status=dead}}
The locomotive, BNSF 1205, was originally built in 1957 as Canadian Pacific 8637 (renumbered 1544 in the 1980s), a GMD GP9 locomotive.{{cite web |last1=Franz |first1=Justin |title=BNSF Donates Hydrogen Test Locomotive To Oklahoma Museum |url=https://railfan.com/bnsf-donates-hydrogen-test-locomotive-to-oklahoma-museum/ |website=Railfan & Railroad Magazine |access-date=30 December 2023 |language=en-CA |date=15 August 2023}} In 2006, it was rebuilt into a GG20B for the Canadian Pacific, 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.{{cite web|title=Pictures of BNSF 1205|url=http://www.rrpicturearchives.net/locoPicture.aspx?id=120230}} To date, it is the largest land vehicle on earth to be powered exclusively by hydrogen fuel cells.{{Cite web|url=http://www.fuelcelltoday.com/news-events/news-archive/2012/february/partnership-to-produce-five-fuel-cell-mine-locomotives|title = Partnership to Produce Five Fuel Cell Mine Locomotives}}
In 2023, the locomotive (without its hydrogen components) was donated to the Oklahoma Railroad Museum, which plans on using it as a control car and for electricity generation on the end of its excursion trains.{{cite web |last1=Garrison |first1=John |title=BNSF’s first hydrogen locomotive |url=https://www.trains.com/trn/railroads/locomotives/bnsfs-first-hydrogen-locomotive/ |website=Trains |access-date=30 December 2023 |date=31 August 2023}}
