The SJ Class T46 is a
diesel-electric locomotive used by
Malmtrafik for
shunting at
Kiruna in Sweden. Four locomotives were built by
Nyquist & Holm (NOHAB) as upgrades versions of
T44 in 1973–1974. The T46 features more powerful engines and six,
Co′Co′, instead of four axles. It is the most powerful diesel locomotive used in Sweden. The locomotives are still in use, and three of the engines were supposed to be upgraded in 2007, but the company that was rebuilding them went bankrupt.
LKAB's own workshops at Notviken are rebuilding them instead.
