Quality and safety in constructionis priority at LEONHARD WEISSGeneral contractor network construction
Signals are indispensable controls in rail and road traffic. They ensure optimum road and railway user safety. It is important that the signal itself has a secure foundation.
A genuine innovation has been created with "TECDOWN." In addition to ensuring a short Construction period with minimal operational interference in production, the system makes compensation of dimensional tolerances, bypassing of local obstacles and adaptation to different soil conditions possible. A long service life is ensured for future use thanks to the great accuracy of fit as well as the maintenance-free construction that resists settling.

high speed project Digital Control Centre Zwieseler Spinne
Pure nature and digitalisation of railway in the region Bayerischer Wald
Customer: PINTSCH GmbHConstruction period: 14 months Year of Construction: 2022–2023
- In addition to the traditional underground cable works and signal foundations for the new control centre we have been awarded the contract for the simultaneous construction of railway and road, as well as for the landscape management. In connection with the project there will be further projects like the construction and foundation of five buildings for control and switchgear facilities and two hot box detection facilities. The challenges are the particularities of the pilot project, the planning legwork, the rocky ground, and the sensitive switch gear technology still in operation.
- Further challenges are logistics, access ways and the delivery of material to the very remote, one-track railway line, as well as the requirements of environmental protection and species conservation.
- Signal foundations (prefabricated concrete parts and partially foundations on rocky ground)
- Signal foundations TecDown
IECC Osterburken
Underground cable engineering, signal foundations and environment measures for the construction of a new integrated electronic control centre
Customer: DB Netz AGConstruction period: 24 months Year of construction: 2021–2022
- The main construction performances in the field of underground cable engineering are carried out during a complete shutdown of the lines 4900 and 4120 between Möckmühl and Osterburken, from Seckach, to Osterburken, up until Eubigheim the underground cable engineering performances like track crossings, cable chutes, construction of side paths, cable ducts, signal and signal bracket foundations are continuously carried out by the construction site team during the six weeks in day and night shifts around the clock. The total length of the construction site amounts to approx. 25 kilometres of track. After the termination of the complete shutdown the pull-in of about 120,000 metres of control, communication, and safety system cables is started. For the realisation of the new cable duct, a new side path construction must be produced at various railway embankments by means of ballast boards, in order to enlarge the slope shoulder. At the railway station Osterburken a new point is installed by LEONHARD WEISS during the shutdown for taking into operation in 2022 for a better interconnectedness of the tracks. After taking into operation the dismantling of the old technology is carried out during subsequent nightly shutdowns with the aim of terminating the project at the end of 2022.
Particularities
- New construction cable duct: 6,500 m
- New construction side paths: 1,600 m
- New cable crossings: 41 pcs.
- Signal foundations: 73 pcs. (driven casing pipe foundations, concrete monoliths, small foundations)
- Signal brackets: 3 pcs. with pile foundations DN700 and sheet pile boxes
- Laying of control, communication, and safety cables: 120,000 m

IECC Merseburg, 2nd construction phase
New signals for Merseburg
Customer: DB Netz AG, LeipzigConstruction period: 1 month Year of construction: 2017
- The 24 signal foundations were partly carried out by means of a sleeve for instant installation, in order to be able to install the signal directly afterwards. The foundation lengths of the individual signal foundations were measured according to the corresponding soil characteristics and varied between 4.50m and 7.50m in different sections. Individual driven steel tubes had to be driven to the final depth by means of relief wells. The brining into service of the signalling technology took place in mid-May 2017
