This route first opened in 1886 and the nostalgic "Molli" steam trains still travel along the 15.4-kilometre stretch between Bad Doberan via Heiligendamm to the Baltic resort of Kühlungsborn. The historic narrow-gauge railway with a gauge of 900 mm carries more than 585,000 passengers a year. A ride on the "Molli" steam trains is a unique experience.
