Class U special wagon
From Wikipedia, the free encyclopedia
The International Union of Railways groups all special classes of railway goods wagon (less those in classes F, H, L, S or Z) into Class U in its goods wagon classification system.
These are:
- Bulk goods wagons for transporting powders, etc.
- Dual coupling wagons for joining wagons with different coupling systems
- Barrier vehicles for joining wagons with different coupling systems
- Well wagons, including low-deck wagons and Schnabel wagons
- Self-discharging hoppers with loading hatches
- Trials vehicles for RoadRailer and Kombirail[1] systems for intermodal transport.
Between 1964 and 1979 bulk goods wagons for liquid and gaseous materials (tank wagons) were included in Class U before being reclassified in 1980 as Class Z.
