An electro-diesel locomotive (also referred to as dual-mode locomotive) is powered either from an electricity supply (like an electric locomotive) or by using the onboard diesel engine (like a diesel-electric locomotive).
В настоящее время используются в ЮАР (серия Dual-Mode Locomotive Class 38), США (DM 30 AC для Long Island Rail Road LIRR, P32-AC-DM для Metro-North Railroad) и других странах.
