While Big Boy No. 4014 used to run on coal, it has been converted to run on No. 5 oil. The locomotive’s water capacity is 24,000 gallons. That water is heated into steam, which is piped into a cylinder and causes a piston to reciprocate, or move in and out. That piston motion powers the locomotive. The heat from the locomotive can be felt standing next to it. – Sarah Kocher/Albert Lea Tribune
