System Description

The Sersa Maschinenller Gleisbau AG ensures smooth train traffic on the track of the metre gauge railways by maintaining them with state-of-the-art machinery and innovative measuring technology.

For the systematic maintenance work, ballast is drawn in from the ballast flanks with ballast graders or unloaded ballast is distributed. Levelling and tamping machines are used to correct the track in direction, height and over-height. For quality control, recording runs as well as re-measurements are carried out with the track measuring device Mephisto.

Finally, the track is cleared of the ballast again with the ballast levelling machines. The ballast flanks are laid correctly and the sleeper compartments are compacted. The track maintenance machines are operated by specially trained and experienced teams of machine operators.


The machines can be used in very tight radii, on steep gradients as well as in rack and pinion tracks. Various coupling systems are available. The tamping machines are equipped with the absolute measuring system PALAS for high accuracy without limiting the performance. For the machining of large turnouts, a third strand lifting system is available. 2 ballast grading machines are equipped with a silo for the lifting and moving of ballast.
