NSB Di 7 634 is a diesel-hydraulic locomotive used by Norges Statsbaner (NSB) from 1993 until 1996. The loco was an SJ T44 bought from Statens Järnvägar and used on Ofotbanen when the Di 2-locomotives where not powerful enough any more. The unit was sold to Malmtrafikk when it took over freight operations on Ofotbanen in 1996, where it became MTAS 6, along with a T44 numbered MTAS 5. While in service with NSB it had the yellow and red livery typical for shunters.

The locomotive was built by NOHAB, based on a design from General Motors Electro-Motive Division. The 12 cylinder 127 liter General Motors engine produced 1,235 kW at 835 RPM, and had a traction effort of 220 kN.
