Short description of the project:
The project included two work areas on railway nr. 20, and both were route sections with faulty substructures. Due to the continuous deterioration of the sections, unilateral sinkings, twists, surface and directional flaws appeared, and it led to a speed limit of 40 km/h being introduced in the affected sections. The flaws could only be repaired by repairing the substructures. Besides the new substructures, new superstructures were also created.
The substructure of section Veszprém – Herend was reconstructed using earthwork technology, complemented by soil stabilization. The 1 trough bridge in this section was reconstructed into a frame bridge, and the drainage system was renewed.
In the section Szentgál – Városlőd-Kislőd, 6-10 m long embankments contained a significant amount of slag, so nearly the whole embankment had to be broken down and had to be rebuilt. The ditch got a special, three-dimensional erosion protection mattress. The drainage system was renewed and complemented here, too.
During the conversion, the overhead electrical supply, signalling and telecommunications systems were renewed and reconstructed, too, and in both sections, new power line poles were erected.
The biggest tasks of the project were carried out during the 2.5-month long track obstruction. As a result of the project, the railway line can be used by the scheduled trains with the original speed again.
