Class 93 is a tilting two-carriage diesel multiple unit used by SJ Norge for passenger trains on non-electrified stretches of the Norwegian railway network. Used on the Nordland Line, the Røros Line and the Rauma Line, they were purchased to replace the aging Di 3 locomotive-hauled trains. The Class 93 was produced by Bombardier, and is part of the Talent family. Fifteen units were delivered between 2000 and 2002.

A tilting train is a train that has a mechanism enabling increased speed on regular rail tracks. As a train rounds a curve at speed, objects inside the train experience centrifugal force. This can cause packages to slide about or seated passengers to feel squashed by the outboard armrest, and standing passengers to lose their balance, or in such excessive speeds, could even cause the train to derail. Tilting trains are designed to counteract this by tilting the carriages towards the inside of the curve, thus compensating for the g-force. The train may be constructed such that inertial forces cause the tilting, or it may have a computer-controlled powered mechanism.
