Transco narrow-gauge railway of the NEAT building site in Sedrun. This rotation dumper is used to unload wagons with material from the tunnel (rocks and sand). Several wagons are entirely turned upside down to unload them. The material is then transported with conveyor belts to another station where it is loaded on 1000 mm wagons which go down the mgb line to Disentis (and further on to Chur on the RhB).
