Masovian Railways (; KMKOL) is a regional rail operator in the Masovian Voivodeship of Poland.
History The company was founded in 2004 as a joint venture of the Masovian Voivodeship, with 51% shares, and the then government-owned PKP Polregio, with 49% shares, to handle local passenger traffic in the Voivodeship. It started operating on 1 January 2005. Since the end of 2007 Masovian Railways has been fully owned by the Masovian Voivodeship.
In November 2025, the Warsaw-Lublin rail line was the target of explosive sabotage during the Russia-Ukraine conflict. The rail was reportedly sabotaged to prevent resources from being given to Ukraine.
Rolling stock At the beginning, the rolling stock consisted of old electric multiple units taken over from the Polish State Railways. These were gradually modernised, and further units purchased second-hand from other operators. Later on, the company purchased or leased new rolling stock. As of 2010 the Masovian Railways had just under 200 PKP class EN57, five EN71 and two EW60. Additionally, the company purchased seven DB Class 627 railcars and four 628 diesel multiple units to serve on non-electrified routes.
In 2008 the company bought 10 modern Stadler FLIRT EMUs and 26 Bombardier Double-deck Coaches along with 11 cab cars. At the beginning, Masovian Railways leased 11 EU07 electric locomotives from PKP Cargo to work these trains, since 2011 they are pulled by TRAXX P160 DC purchased from Bombardier.
In 2011 the company bought 16 PESA ELF EMUs designated class EN76 and 4 SA135 DMUs also from PESA.
In January 2018 the company ordered 71 Stadler Flirt EMUs.
As of May 2021, the company owns, leases, or hires the following rolling stock:Koleje Mazowieckie: Majątek Spółki (in Polish)
