 Similarly it was used extensively on the Saxon narrow gauge system west of Dresden to transport china clay to Meissen.Using rollbock technology requires that the narrower gauge network must be built to a structure gauge large enough to accommodate the loading gauge of standard gauge wagons, and that negates one of the cost advantages of narrower gauge construction.The system was tested for the narrow gauge railways in Saxony around 1900 but it found only rare application - tracks requiring higher transport capacity were rebuilt to standard gauge instead.
