Tropenbahn

Machine-translated from the German article

The Tropenbahn, also called the Tropen-Schwebebahn, was a concept for a monorail suspension railway to open up the German colonies. Parallel to the detailed planning for the Wuppertal Schwebebahn, which was approved in 1894 and opened in 1901, its inventor Eugen Langen developed the railway he named the Tropenbahn from summer 1895 onward. It was intended as a lighter and cheaper railway for special uses, in particular for deployment as a "transport railway for colonial purposes" as well as a military transport facility.
