Łódź Cross-City Line

Historically, this 5.27 kilometres (3.27 mi) long section was opened in 1865 as a part of the Łódź Factory Railway.

[3] The old buildings of Łódź Fabryczna and Niciarniana stations were demolished, tracks were dismantled, and ground works began.

Łódź Polesie is proposed to be located near the intersections of Ogrodowa and Jan Karski streets, near the Manufaktura shopping gallery (former site of I. Poznański's textile factory).

[9] On 28 November 2016 PKP PLK started a bidding process to select the contractor for the design and build of the cross-city tunnel between Fabryczna and Kaliska stations.

[10] In September 2017, the contract was awarded to a consortium of Energopol Szczecin and Przedsiębiorstwo Budowy Dróg i Mostów (eng.

Road and Bridges Construction Company) from Mińsk Mazowiecki, starting with an offer estimated at 1.59 billion PLN.

The third stopping point will be located in the place of the second large drilling chamber, located within the quarter of Włókniarzy Avenue, Drewnowska St. and Kasprzaka St, initially set as an underground branch post, with access points near Włókniarzy Avenue and Kasprzaka St.
