New Major Project for solid-state interlocking (SSI) S1 North
Following the successful completion of the major projects Suedbahn and SFS 1733, SPITZKE’s railway infrastructure company has two new major projects on the agenda. One is being carried out in connection with the enormous Stuttgart 21 traffic and urban development project. The other one is taking place in the far north of Berlin: solid-state interlocking S1 North.
The extensive DB AG project on Berlin’s S-Bahn line 1 will stretch from the Frohnau to Oranienburg stations. SPITZKE will carry out all part services – from structural engineering over the road, the foundation to the catenaries. In a nutshell: For the major project, SPITZKE, as a system supplier for railways, will implement everything necessary for the later commissioning of the solid-state interlocking system (SSI). This also includes the dismantling of the old infrastructure for all electrical technology, carrying out track measures, the subsequent equipping of the SSI outdoor system as well as the technical installation of track switches.
All services for the solid-state interlocking for the S1 from one source
All of SPITZKE’s expertise is needed to carry out the tasks included in this project. The enormous range of services includes, among other things, the installation of track heating systems, track renewal, foundations for the catenary masts and signal brackets, however also retaining walls and cable bridges as well as the construction of paths and contact-rails tasks. This work is being carried out by the equipment/electrical engineering and major projects/engineering construction departments. The entire scope of services is provided by a single source with our own groups from our branches in Großbeeren and Leer. This includes: overhead lines, electrical power systems, track current, civil and special underground engineering, foundations and tracks.
SPITZKE was awarded the contract for this project in November 2021. Since then, the planning stage has been in full swing. The construction work will begin on February 12th, 2022 when the first closure period starts. In preparation for the construction of the SSI for the S1, the first steps will include the renewal of the tracks and the contact rails in the section Frohnau – Hohen Neuendorf (including 2 tracks at the Frohnau station), as well as the tracks in Birkenwerder. The project will continue until the mid 2024.
