Wiener Stadtwerke snow clearing trailer type spa1 no. 9046 (built in the 1970s by Gräf & Stift). It was coupled behind a snow clearing tram to clean the road next to the tracks - now with a much more comfortable cab for the operator. Length 2.57 m, weight 1 t. Such vehicles aren't used any more because the Wiener Linien aren't responsible for road snow clearing any more.
