Tender Car

Steam locomotives often haul a tender, which is a special railway car designed to hold the locomotive's fuel (wood, coal, or oil) and water. In America, tenders are sometimes called coal-cars. Steam locomotives consume large quantities of both fuel and water, so tenders are necessary to keep the locomotive running over long distances. A locomotive that pulls a tender is called a tender locomotive. Locomotives that do not have tenders and carry all their fuel and water on board the locomotive itself are called tank engines.
