RAILPOWER Technologies Corp issued a statement on June 1 recalling 59 diesel-battery locos from the GG-series, including Green Kids and generation I, II and III models, and requesting that owners temporarily cease operating them.

The action was triggered by a fire in a Green Goat in Texas on May 30. RailPower immediately began an investigation into the cause of the fire 'to determine temporary and permanent solutions.' The company had already completed an in-depth study of potential problems in generation III Green Goat locomotives and said it 'will install a new version of software for battery pack monitoring and implement some mechanical improvements for additional protection.' RailPower said the 54 road switchers it has supplied are unaffected.
