When the passenger locomotives were given more powerful motors, they were designated Dk. They had a maximum speed of 100 km/h. This is the last series of locomotives that was built new, all later types have been rebuilt, except the one-off experimental subtype Dr. The last Dk loco was built in 1943 and concluded eighteen years of D production. When the production of Da-locos started in 1953, the Dks were rebuilt to the same engine, and received the designation Du. The last use of Dk was in 1975. In total 117 have had the Dk designation, of which 73 were built as Dk.
