System Description

The Sersa Maschinenller Gleisbau AG ensures the efficient renewal of the track with a modern, innovative machine fleet that is adapted to the requirements of metre-gauge railways.

The RM76 CAPRICORN ballast cleaning machine uses a chain to convey the ballast into the screening plant. The cleaned ballast is then reintroduced into the track bed. This efficient process protects both environment and resources. The polluted debris is conveyed and removed on ballast wagons. The RM76 CAPRICORN in combination with the gantry crane system MUNGG enables complete track renewals (including track and sleeper replacement) even during night closure.

The AVW-2 TYREX rail-bound excavating and loading excavator is used for ballast replacement and subgrade rehabilitation. For the removal and installation of the track yokes, the gantry crane system MUNGG or the track crane KRC458 is optionally used in the night barrier.

Tamping machines and road graders are used to complete the work.

For all other renovation work, various special machinery, such as pick hammers or walking excavators, are available.


The machines can be used in very tight radii, on steep gradients and, for the most part, in rack and pinion tracks. Very experienced and trained teams operate for all works.
