Civil engineering and track reconstruction
Extensive formation rehabilitation work was carried out on the 5362 Buchloe – Lindau Hbf line between April and September 2009. The measures were carried out with the help of the formation rehabilitation machine RPMW 2002. At the same time, the tracks were converted mechanically using the assembly line method, for which the conversion vehicle VFW 2001 was used. Conventional track renewal was carried out on a good four kilometers of track, including ballast renewal and the installation of various formation protection layers.
In the civil engineering segment, deep drainage was carried out. The interaction of all these measures ensures smooth rail traffic on the said route and thus the mobility of people in the region.
The track work in detail:
- Client: DB Netz AG, Regional Division South
Installation of a subgrade protection layer at 34,072 metres
Mechanical track reconstruction using the assembly line method
4,166 metres of conventional track reconstruction
Bedding renewals
- 26,000 metres of civil engineering work: deep drainage
Working concept
With the use of state-of-the-art machinery and laying technology, the track reconstruction and the installation of subgrade protection layers were able to proceed quickly.
This was necessary on the one hand to keep the impairment of the regular operation of the track as low as possible and on the other hand to keep the load-bearing capacity of the track system permanently high. With regard to the latter, extensive deep drainage was also carried out, which ensures a stable track position in any terrain.
Construction vehicles used
RPMW 2002
The RPMW 2002 grade improvement machine enables a total renovation by separating the soiled ballast bed up to a thickness of about 350 millimeters with subsequent bedding material processing including ballast recycling within the machine and renewing the substructure layer up to a thickness of 500 millimeters. The machine is equipped with two excavation chains. In this process, gravel and soil are removed and processed separately to prevent the two materials from mixing.
For even better material recycling, the Wiebe Group also owns an RPMW 2002-2 with an integrated high-pressure washing system.
VFW 2001
With the VFW 2001 reconstruction train, track coverings of up to 350 metres per hour can be carried out during track construction, reconstruction and dismantling.

Due to the length of the section of track, it was important to work purposefully and efficiently so that regular track use could take place again as quickly as possible.
Despite all the speed, however, our greatest concern is always the quality of the construction measures, as it plays a major role in the safety guarantee of the client – in this case Deutsche Bahn – towards its customers. Thanks to our special emergency vehicles, we were able to reconcile this requirement with optimal time management. Nothing stands in the way of a train trip to Lake Constance again.
