SJ Tc is a diesel-hydraulic locomotive used in Sweden for line service and snowploughing. Twenty locomotives were built for Swedish State Railways (Template:Lang-sv) in 1969-71 by Nydquist & Holm for combined freight, line service and snowploughing service, along with 10 larger Tb locomotives. SJ used the locomotives for freight and track work trains during the summer and for snow removal in the winter. In 1984, the locomotives were transferred to the service fleet and they were then mainly used for track work trains.

When the Swedish Rail Administration (Banverket) was created as a demerger from the Swedish State Railways in 1988, all Tc locomotives were transferred to the latter. Since the early-2000s, many units have been taken out of service. As of 2017, only three Tc locomotives remain in operation, two operated by Strukton Rail AB and one operated by Infranord.

They are fitted with a lifting plate in between the driving axles which allows the locomotive to lift itself off the tracks and so be turned around. This allows the snowploughs to always face in the running direction. Along with this, the Tc locomotives are capable of working in a multiple unit arrangement with other Tc locomotives.

Power for the Tc is provided by a 600 hp (450 kW) diesel prime mover which is manufactured by German engine builder Deutz.
