Kleinbahn im Rheinpark

The VWZ-600 petrol locomotive is powered by a Porsche type 616 industrial engine. Its front is modeled on the Porsche 356, while its shape and paintwork recall a TEE railcar train. The year of construction is given as 1959; it was built by the Sollinger Hütte in Uslar near Hannover, according to vehicle records between 1959 and 1971. It was purchased from Dortmund in September 2001, with Westfalenpark listed as its origin, and is one of the Porsche locomotives that already ran at the 1971 Bundesgartenschau. After more than 2,000 hours of restoration, it runs on special occasions and, according to another source, also on Sundays and public holidays.

For the first Bundesgartenschau, the KVB operated a 381 mm gauge park railway here that attracted international attention. It ran with three Krupp steam trains named "Rosenkavalier", "Männertreu" and "Fleißiges Lieschen", which had survived the Second World War in the engine shed of the Köln-Frechen-Benzelrather Eisenbahn. As early as 1958, operations were discontinued for cost reasons, the tracks were removed and the trains sold to Great Britain. Since 1976, "Fleißiges Lieschen" has been running as "Black Prince" on the Romney, Hythe and Dymchurch Railway.

The two-track Tanzbrunnen station lies directly beside the event area of the same name; the trains pass a large nearby playground without stopping. The Thermalbad halt is located directly in front of the Claudius-Therme spa, shortly before which stands the two-track depot, resembling a long car garage. Its rear entrance was closed during a modernization around 2000 and has since been partly dismantled. At the Rosengarten halt are the Kölner Jugendpark, a mini-golf course and a children's bumper car track; the Rheinpark chairlift, closed in 2001, also once had a station here. In addition to the full circuit, rides on partial sections are also possible.
