PKP Intercity ordered 20 of the seven-car non-tilting emus in 2011 at a cost of €400m, and the trains will be maintained by the manufacturer under a 17-year deal worth a further €265m, which includes the construction of dedicated maintenance facilities for the fleet.

Following the completion testing at Żmigród, mainline trials will begin on the Central Main Line (CMK) between Warsaw and Zawiercie in Silesia. The 250km/h trains will enter service on Warsaw – Gdansk, Warsaw – Wroclaw and Warsaw – Krakow/Katowice EIC Premium services in December 2014. These routes are currently being modernised to allow the new trains to operate at higher speeds.

Following the completion of the CMK upgrade in 2015, which includes the installation of ERTMS Level 2, it is likely the trains will be able to operate at up to 230km/h on this route.

PKP Intercity has recently announced that fares for EIC Premium services will start from Zlotys 49 ($US 15.50).
