A German railway in German East Africa housed the Phantom Train-weapon which prevented the Allies from taking Morogoro.
In 1916, a small group of Frontiersmen operated on the railway to locate and destroy the weapon. The Frontiersmen, after looting a German camp near the railway, eventually found the secret base where the Germans kept the train.
After a skirmish along the railway, the Frontiersmen eventually succeeded in their mission.
