Between 1981 and 1985 Danish state railways Danske Statsbaner (DSB) took delivery of 37 heavy six-axle diesel locomotives from Henschel. Classed ME and numbered 1501 through 1537, they were among the first diesels featuring AC drive built in quantity. They were used mainly for heavy local traffic in Zealand. In 2017, 33 examples were still in use; three had been scrapped and No. 1501 had been transferred to the Danish railway museum of Odense in 2015. With 42 new ‘Vectron’ electric locomotives ordered from Siemens in 2018 (class EB), all MEs were withdrawn until 2021, being the last diesel locomotives in regular service in Denmark. 27 were sold to Swedish Nordic Re-Finance AB leasing company; they are intended for passenger and freight traffic across Scandinavia. The remaining six examples (numbered 1503, 1505, 1511, 1517, 1522 and 1532), initially also dispatched to Sweden, were finally sold in 2022 to Polish private operator SKPL Cargo (Stowarzyszenie Kolejowych Przewozów LokalnychAssociation for Local Railway Traffic). Currently (October 2023) they are undergoing repairs and overhauls in Ostrów Wielkopolski. Most probably they are intended for leasing. In early October ME 1511 was re-numbered SU175-001 and this class designation will most probably be applied for the remaining five examples. ‘175’ indicates maximum speed, although – according to some sources – it was in fact reduced to 130 km/h.
