The South African Railways Class 61-000 of 1959 was a diesel-hydraulic locomotive. Between May and July 1959, the South African Railways placed seven Class 1-DH Henschel type DH-1420 diesel-hydraulic locomotives in service to also gain experience with other forms of diesel motive power than diesel-electric. The locomotives were later reclassified to Class 61-000. In 1971, six of them were sold to Rhodesia Railways.
