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.
- New construction cable duct: 28,000 m
- Production of track crossings: 850 m
- Mounting of cable assembly chutes: 160 pcs.
- Signal foundations (partly on rocky ground): 99 pcs.
- Ramming of cable duct stabilisation with ballast supporting slabs: 3,600 m
- Laying of cables: 288,000 m
- Underground cable works for hot box detection facilities: 2 pcs.
- Conversion of level crossings: 9 pcs.
- Outside facilities and foundation of buildings for control and switchgear facilities: 4 pcs.
- Outside facilities and foundation of buildings for control and switchgear facilities and operation building operated by traffic controller: 1 pc.
