A mobile track surfacing machine comprises a machine frame unit comprising two machine frame parts linked together to form the unit. The machine frame parts have facing ends coupled together to permit the machine frame parts to pivot in relation to each other in a plane substantially parallel to the track and a single undercarriage supports each machine frame part for mobility on the track in the region of the machine frame part end opposite to the end linked to the other machine frame part. A track tamping unit is mounted on the rear machine frame part.
