Gravel dumper type Uas with no. 33 54 9300027-7 CZ-RCO (Railco) in Wuppertal-Oberbarmen on 11th of June 2013.
Most other companies classifies such cars in category F, even Railco does it on their web-site, but wrote "Uas" on the car itself. On the given web-site, exactly this car is pictured as example. If you magnify that picture, you'll see that this car was former owned by ŽOS Zvolen from Slovakia - there it was correctly signed as "Fas"...
