The modernization of the Łódź railway junction (TEN-T), stage II, section Łódź Fabryczna – Łódź Kaliska/Łódź Żabieniec in Poland, started in 2018, is going forward! It is the next phase of the Łódź tunnel project started in 2011, with the construction of 16 m deep underground Łódź Fabryczna railway station and cut & cover tunnel connecting Łódż Fabryczna with the Łódź Widzew station.
The Łódź Fabryczna station will be connected to the Łódź Kaliska and Łódź Żabieniec stations with deep TBM tunnels. The City of Łódź has been waiting for this connection over 100 years! SWS provides TBM and MEP design for all project phases.
The sections under construction will consist of one double-track tunnel with a diameter of 13.04 m and a length of approx. 2.8 km (including approx. 600 m of underground stations and junction chambers) and 4 single-track tunnels with a diameter of 8.83 m and a total length of approx. 3,7 km (including about 540 m of underground stations and junction chambers). The maximum depth of the tunnel will be over 30 m.
The tunnels will be made with two TBM machines, the larger one with a diameter of 13.04 m and a smaller one with a diameter of 8.83 m. The scope of the SWS Engineering project includes building permit design and construction design for tunnel works performed with the TBM machines and for all MEP installations, both in the tunnel and at the stations.
In accordance with the original contract, 2 stations are to be built on the tunnel route, the Łódź Śródmieście station and the Łódź Polesie station. As announced recently, PKP PLK plans to add a third station called Łódź Włókniarzy station in place of the current Włókniarzy chamber.
Thanks to this investment, it will be possible to comfortably commute from one end of the city to the other in just a few minutes. National connections through the center of Łódź will be improved, and regional and agglomeration connections will gain a new quality and greater competitiveness thanks to the possibility of direct access to central places in the city. The tunnel under Łódź will create the first element for future high-speed lines between Warsaw and western parts of Poland.
