"Graf Schwerin-Lowitz" is a narrow gauge 0-6-2WT (Well Tank) with a tender built in 1908 by Arnold Jung Locomotivfabrik of Germany. It was operated by the Mecklenburg-Pommersche Schmalspurbahn until worn out then rebuilt in 1981 and given a new boiler in 1993. Due to its small size it's unable to pull trains on the stiff grade beyond Dol-y-Gaer. During summer 2016 the engine was found located inside the Pant workshop and may not be serviceable.
