The trailing work vehicle carries apparatus for fastening rails to the laid ties and an operating unit for lifting the track and for tamping the ballast under the ties trailing the apparatus for fastening the rails to the laid ties, the operating unit being intermittently displaceable on the trailing vehicle in the operating direction. A displacement drive connects the operating unit to the trailing vehicle for intermittently displacing the operating unit.
