For the opening of the 6.6 km (4.1 mi) long railway line from Doberan to Heiligendamm the DHE had procured two 'tramway' locomotives, which were given the numbers 1 and 2. The long section through the town in Doberan in particular made the procurement of such engines sensible. When the private railways were nationalised in 1890 the locomotives were renumbered to 1001 and 1002. Not long afterwards, it became clear that the locomotives were not able to cope with the rising levels of traffic as they could only haul a three-coach train. So in 1891 and 1898 Class XIX engines were procured. The tramway locos were retired in 1916.
