Vaega Autu ole GE 7FDL Engine
O le GE 7FDL fa'asologa o le fa-stroke medium-speed afi tiso na gaosia e le General Electric (GE). O lo'o fa'atulagaina muamua mo ta'avale locomotive nofoaafi, ma e fa'atatau fo'i i faiga fa'aola o le gataifale ma iunite fa'atupu eletise. O lo'o i lalo ona fa'ata'ita'iga fa'apitoa fa'apitoa ma fa'amatalaga au'ili'ili o fa'ata'ita'iga fa'atasi ai ma le aofa'i o pa'u.
