The Spanish Army purchased a batch of German narrow gauge (80cm) rolling stock after WWI, some of the locomotives are still preserved for display in army barracks.
The bigger locomotive is an Orenstein & Koppel, there is another one restored with a cargo wagon and passenger car.
The smaller one, as its plaque clearly states is a Henschel, dubbed "Tigris" as, it was said at the time, it was intended to be used in an annex spur of the Berlin-Baghdad railway running from Baghdad to Basrah along the Tigris river.
The locomotives were deployed in Morocco during the Rif war, supporting operations in the Melilla area.
Afterwards they were used for training purposes in the Spanish mainland.
