A fireless locomotive is, as the name suggests, one which does not use fire; It does not need to burn coal to create steam. The engine has instead a high-pressure steam vessel, in which it collects ready-made steam from a distant steam/boiler plant. Such bg locomotives, with 0-4-0 wheel arrangements, are used in places like chemical plants, where sparks flying out of the locomotive chimney could prove to be a major fire hazard. As the capacity of the engine is limited to the amount of steam the boiler can hold, the utility and range of these machines is necessarily very limited and speed is very low. This particular fireless locomotive was used by the Sindri Fertilizer works of Bihar. Preserved at National Railway Museum, New Delhi.
