Class U special wagon
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:
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.
The powder wagon is a special form of bulk goods wagon designed to transport goods in powder form. These wagons are pneumatically unloaded, usually by using compressed air. For goods that might react with oxygen in the compressed air, nitrogen is used instead. These wagons are used for bulk commodities, such as cement, that are so fine-grained they cannot be poured, or at least do not pour very well, and so cannot be emptied under gravity. Under the UIC system they are given the category letter U and index letter c. They do not normally have their own compressors but must be unloaded using external equipment.
This group has a large variety of different types of wagon that range from the two-axle low deck wagon to the 36-axle Schnabel wagon.
The current designation for all low deck wagons is Ui, which can be supplemented as necessary by the index letters a, aa, k, kk or s. The load limits on low-loading wagons are not indicated by letters. The former German wagon classes were St and SSt.
In 1998 the Deutsche Bahn had a total of 180 well wagons of 43 different types. They are used to move very large and heavy goods that would exceed the loading gauge on flat wagons. Such loads typically include: combine harvesters, generators or narrow gauge vehicles.
The largest low-loading wagons are designed as Schnabel wagons, made from two completely separate sections. Each section rests on multiple-axle bogies or groups of bogies. The two sections each support a beak-shaped carrying arm which, in turn, supports one side of a low-loading platform or is directly fixed to the outsize load to be transported. In the latter case the load becomes temporarily part of the vehicle itself. The wagons have hydraulic equipment with which the load can be raised or lowered in order to manoeuvre it past obstacles. There are about 30 examples of Schnabel wagon in Europe, North America and Asia.
