Łódź Cross-City Line

A Łódź Cross-City Line is a planned railway line running through the centre of the city of Łódź, Poland, intended to connect three major railway stations of the city: Łódź Kaliska, Łódź Fabryczna and Łódź Widzew. It consists of two sections: open-air section between Łódź Widzew and Łódź Niciarniana stations, and a tunnel, currently reaching Łódź Fabryczna station.

Existing sections

Łódź Fabryczna - Łódź Widzew

Historically, this 5.27 kilometres (3.27 mi) long section was opened in 1865 as a part of Łódź Factory Railway.[1] - a company established by Karl Wilhelm Scheibler and Jan Bloch. The railway allowed Łódź to be served by trains running on the Warsaw-Vienna railway.[2] In 1903 Łódź Widzew station was opened, serving both "factory line" to Łódź Fabryczna and a circular line leading to Łódź Kaliska station, both of which operated on different track gauges. The track gauge was unified during World War I. Before World War II a third station - Łódź Niciarniana - was opened. The line was electrified in 1954.

In 2011 the section was closed, as the general reconstruction began.[3] The old buildings of Łódź Fabryczna and Niciarniana stations were demolished, tracks were dismantled, and ground works began.[4] In 2012 the construction of a cross-city tunnel from Łódź Fabryczna to Łódź Niciarniana stations has begun, along with the construction of new stations. These works required replacing a secured level crossing with an underpass for Niciarniana street and replacing the platforms with a new island platform over the underpass. On 11th of December 2016 the section was reopened,[5] being served by ŁKA commuter trains, Polregio regional trains and PKP Intercity trains.

Sections under construction

Łódź Fabryczna - Łódź Kaliska
Scheme of planned cross-city tunnel between Fabryczna and Kaliska stations.

In 2009 representatives of the City of Łódź, Government of Łódź Voivodeship and PKP PLK signed an agreement for creating a feasibility study for building a cross-city tunnels between Łódź Fabryczna and Łódź Kaliska stations: one for regular rail services, other for high-speed rail as part of planned line "Y" from Warsaw through Łódź to Poznań and Wrocław. In 2010, a contract for a feasibility study into a conventional rail tunnel was awarded to the Spanish company, Sener.[6][7]

The plan for conventional rail tunnel consisted of a double-track tunnel running between Łódź Fabryczna station and railway line no. 15, running between Łódź Kaliska and Łódź Żabieniec stations, with the possibility for both stations to access the tunnel. The plan proposed the construction of two additional stops: Łódź Śródmieście and Łódź Polesie. Łódź Śródmieście will be located under the intersections of Zielona and Zachodnia streets with Kościuszko Avenue. 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). The double-track connection with Kaliska and Żabieniec stations will be provided by an underground branch post Łódź Włókniarzy, where the tunnel will split into 4 single-track tunnels - a pair for each station.[8] The total length of the tunnel is estimated to be approximately 2.7 kilometres (1.7 mi).[9]

On 28th of November 2016 PKP PLK started an bidding process to selecting a contractor for designing and building the cross-city tunnel between Fabryczna and Kaliska stations. The maximum cost of the contract was estimated at 2.17 billion PLN, with a proposed construction period of between 48 and 51 months.[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.[11] The contract was signed on the 28th of December 2017.[12]

The construction works began in August 2019, starting with construction of drill chamber in the area between Odolanowska and Stolarska streets in Polesie district. From there two tunnel boring machines will begin drilling the tunnel toward western end of Łódź Fabryczna station (double-chamber) and toward Łódź Kaliska and Łódż Żabieniec stations (single-chamber). The tunnel is expected to be complete sometime in 2022 or 2023.[13][14]

In February 2020 a plan for a third stopping point - Łódź Koziny - was approved. Said stopping point will be located in a place of the drilling chamber, with access points near Włókniarzy Avenue and Kasprzaka St. However, construction of the stopping point will commence after 2022 as part of second phase of upgrading the railways in Łódź.[15]

gollark: I reject Forth and substitute RPNCalcV5.
gollark: osmarkscalculator™ would also have advanced numerical approximation-of-things features, because making it able to *exactly* solve all things ever is actually nontrivial.
gollark: I suppose onboard programming capability would be nice, so maybe just some sort of simple macroey support in the calculatorial language.
gollark: You can do useful things without programming it.
gollark: You could also just upload programs from a computer, if you had more time, I suppose.
