Viewed from a waterfall on the Avalanche Peak track, KiwiRail banker locomotives DXC5385-5419-5520 lead a 'Silver Fern' railcar out of Arthur's Pass yard. The train will shortly enter the 8.5km long Otira Tunnel, which is on a formidable 1 in 33 gradient. Although traveling in the downhill direction, the bankers are attached as the railmotor does not meet fire suppression requirements. The three 'Silver Fern' railcars were built in 1972, this one is RM24, operating a charter for Dunedin Railways.
