A fireless locomotive is a type of locomotive designed for use under conditions restricted by either the presence of flammable material (such as in mines and chemical factories) or the need for cleanliness (such as at a food factory). Thus a traditional steam locomotive is ruled out because of its open fire and the possibility of hot embers ejected from its chimney.
