A 1954 Escher VW-Porsche Kleinbahn Prototyp in the Prototyp in Hamburg.
These little trains were built from 1954 to 1971 and were used in parks and botanical gardens. It pulled 3 cars which had space for 90 passengers. Its not a accident that the design of the locomotive looks like a cross between the legendary TEE train and the Porsche 356. This locomotive was powered by a VW industrial engine and was the prototype of the VW-Porsche trains.
