An efficient and environmentally friendly underground transport system to boost the local economy, trade, and tourism. The railway infrastructure will connect three major railway stations: Łódź Fabryczna – Łódź Kaliska – Łódź Żabieniec. The project includes the construction of two stations, Łódź Zielona and Łódź Ogrodowa.

Two EPB TBMs, 8.8m and 13m dia. excavate a tunnel under the dense urban environment of the city of Łódź in Poland, crossing historic buildings in the city centre with limited overburden. The alignment involves multiple break-in and break-out locations as well as complex TBM assembly and dismantling operations.
