Abstract

The invention relates to a track maintenance vehicle having a levelling attachment secured to a transverse carrier member at its rear. The levelling attachment faces downwards and is at least partially flexible. For achieving satisfactory levelling of relatively loose snow as well as of encrusted or compacted snow, the levelling attachment comprises a leading portion of triangular cross-sectional shape secured to the transverse carrier member along a first triangle side. The second triangle side of this portion is formed as a rigid compaction surface extending downwards and rearwards from the transverse carrier member. Connected to a rear portion of the compaction surface is a plate-shaped flexible portion extending substantially parallel to the second triangle side in the relaxed state, and in a substantially horizontal direction when under load.
