PKP Intercity is a company of PKP Group responsible for long-distance passenger transport. It runs about 350 trains daily, connecting mainly large aglomerations and smaller towns, also servicing most of the international trains.
The company runs the following train categories:
- High-standard trains
- Ekspres InterCity (EIC, EkspresIC) - domestic high standard trains with obligatory reservation
- EuroCity (EC) - international high standard trains, reservation obligatory on domestic routes
- EuroNight (EN) - international night trains with obligatory reservation
- Mid-range trains
- Express (Ex) - domestic trains with obligatory reservation
- Economy trains
- TLK (Twoje Linie Kolejowe, "Your Rail Lines"; until 2010 called Tanie Linie Kolejowe, "Cheap Rail Lines") – cheap express trains with obligatory reservation; some night TLK trains provide couchette and sleeper cars; sleeper cars and couchettes must be reserved. Most of the TLK trains have 1st and 2nd class cars, but some (especially on shorter routes) are 2nd-class only.
- Międzynarodowy (M) - international fast train with TLK standard and fare (lower standard than EuroCity)
- Międzynarodowy nocny - international night train (lower standard than EuroNight)
A high speed rail system is planned.
Fast trains without reservation were transferred to PKP Intercity from PKP Przewozy Regionalne on December 1, 2008. They were all converted to TLK on December 13, 2009.
Most of the EkspresInterCity trains were degraded to the re-introduced Express category on June 1, 2011.
