Szybka Kolej Miejska^[2] (SKM; which translates as 'Rapid Urban Rail') is a mixedrapid transit andcommuter rail (S-Bahn) system in theWarsaw metropolitan area, operated by the city owned company Szybka Kolej Miejska Sp. z o.o. under the management ofPublic Transport Authority in Warsaw on shared, generalrailway lines managed by thePKP Polskie Linie Kolejowe.

The earliest attempts to implement an electrified suburban rail system in Warsaw were made in 1936–37, when theWarsaw Railway Junction and surrounding railway lines were electrified to the national standard of 3 kV DC and high platformelectric multiple units were introduced (which later came to be designatedPKP class EW51).

After World War II, newer EW53, EW54 and EW55 high-platform EMUs were introduced. In 1963,Warszawa Śródmieście railway station was rebuilt into its current form as an underground city station in the city center and in 1967 theWarsaw Cross-City Line was doubled to four tracks to enable separation of suburban and long-distance trains in preparation for the opening ofWarszawa Centralna railway station in 1975. The system went into steep decline from the late-1970s due to the country's serious economic problems and themartial law period. These problems persisted well into the 1990s and 2000s as the fall of communism and the country's transition to a market economy made owning private cars more affordable to the general population and as a side effect of decentralization local authorities preferred to invest in infrastructure used directly by their constituencies.

The Warsaw SKM in its current form was proposed in late-2002, stipulating to use the existing infrastructure of the Warsaw Railway Junction, especially thecross city line with its over 2 km long tunnel running under thecity center and conveniently located underground station, as a cheap substitute for abadly needed second metro line whose construction did not start until 2010.

In order to implement this the then-Mayor of WarsawLech Kaczyński established in 2004 the municipally owned company Szybka Kolej Miejska Sp. z o.o. The company was originally incorporated as a joint venture between the City of Warsaw with 50% shares and the companies Metro Warszawskie Sp. z o.o. with 49% shares and Tramwaje Warszawskie Sp. z. o.o. with 1% shares, both owned entirely by the city and responsible respectively for the Metro and Tram system. As such the company is notably completely independent from the national rail operatorPKP Group, unlikeKoleje Mazowieckie established by theMasovian Voivodeship at around the same time.

The newly formed company was equipped with sixNewag 14WEEMUs which were an extensive modernization of thePKP class EN57 EMUs commonly used on regional routes at the time, with a modern looking body but retaining their original underframes.

A year and a half after being established the SKM initiated its operation with its first trains, opening a single line fromWarszawa Zachodnia along the cross city line toWarszawa Wschodnia and along the Vistula river toWarszawa Falenica. The new service failed to deliver on its promise to serve as a viable replacement due to the poor state of the rail infrastructure. Passengers within the city center preferred the more accessible trams system and few people wanted to use the trains in the southeastern districts of the city. Additionally, while the integrated fare system of the Warsaw Transit Authority offered a large convenience the modern look and relative cleanness of the rolling stock sharply contrasted with the standard found in the Polish railroad; during rush hours most of the slots on the tracks were taken up by regional traffic and the new EMUs suffered from the same technical problems as the ones they were based on.

Due to the initial low popularity of the line the original concept was somewhat altered in 2006 with the line extended outside the administrative borders of the city through theUrsus district into the town ofPruszków to the west and diverted to the district of theWesoła and the town ofSulejówek to the east, turning the service into a suburban commuter network which allowed people in themetropolitan area to quickly reach the city center and conveniently transfer within the city's public transit system. The revised formula proved to be very successful leading the city to take the purchase of all the shares of the company and purchase two more Newag 14WE EMUs. The popularity of the trains was also instrumental in the city negotiating a deal with the Masovian Voivodeship to have Koleje Mazowieckie honor long term tickets of the Warsaw Transit Authority, first along the route of the SKM and eventually within the entire area served by the city's public transit system.

In 2010 the company purchased four brand newNewag 19WE EMUs and opened a new line to the town ofOtwock. Additionally, the Warsaw Transit Authority signed a contract with the Koleje Mazowieckie to operate a line betweenWarszawa Gdańska station on the Warsaw Circumferential Line and the town ofLegionowo under the branding of the SKM, and since 2012 taken over by the company.

In 2011 13 newPesa Elf 27WE EMUs (2011–2012) were purchased. In 2012 a newairport rail link was created running through theSłużewiec office district and a newly opened 1.5 km rail tunnel toWarsaw Chopin Airport.

In 2012 the company purchased 9 six carNewag Impuls 35WE units.^[3]

In 2020 SKM has awarded Newag a contract to supply an additional 21 Impuls 2 EMUs, 6 four car versions and 15 with five cars each. The trains feature air-conditioning, a passenger information system, ticket vending machines and validators,Wi-Fi, USB sockets and anAED defibrillator.^[4]

In January 2022 Newag has delivered the first two Impuls 2 EMUs^[5]

In June 2023, the S4 line was extended toZegrze Południowe, with two new stations: Wieliszew Centrum and Zegrze Południowe. (note: the Wieliszew Centrum station was not yet completed as of the extension's opening, but was completed later on)

Rebuilt from oldPKP class EN57 and extensively modernized giving them a modern look and making them more suitable for carrying large numbers of passengers on shorter routes within the Warsaw metropolitan area. Two units out of eight originally ordered have been sold toKoleje Śląskie. As of 2022, SKM Warszawa operates only 2 14WE units in the fleet however, they have not run any regular service since June 2022 and are used for substitute services when regular trains break down.[6]
	Newag 19WE	4 units	Introduced in 2010. New EMUs designed and built for the SKM
	PESA 'ELF' 27WE	13 units	Introduced in 2011. A version of the PESA ELF EMU adapted for the SKM

As of May 2025 SKM operates 4 regular lines:^[11]

Pruszków – Otwock

The line was established in October 2005, running fromWarszawa Falenica toWarszawa Zachodnia and suspended indefinitely in July 2006 with all of the rolling stock directed to the newly created line S2. In September 2010 the line was re-established and extended towards the town ofOtwock, south east of Warsaw, but only reachingWarszawa Wschodnia, which required most of the potential passengers to transfer there to trains running on the line S2 or regional trains operated by Koleje Mazowieckie to reach the city. The line was extended throughWarszawa Śródmieście andWarszawa Zachodnia toPruszków in December 2010.

Warsaw Chopin Airport – Sulejówek Miłosna

The line was established in July 2006 running fromPruszków throughWarszawa Śródmieście to Sulejówek Miłosna. In December 2010 the line was shortened toWarszawa Zachodnia in the West, with the line S1 taking over the route fromPruszków toWarszawa Zachodnia and further toWarszawa Śródmieście. In June 2012 the line was extended from Warszawa Zachodnia through theSłużewiec office district and a newly opened rail tunnel to an underground station at theWarsaw Chopin Airport. The route assumed its current form on 12 March 2023 due to modernization works at Warszawa Zachodnia station and the Warsaw Cross-City Line.
