You regularly extend the time of "cheap" TLK and IC trains to Pendolino.
And so from 8/06/2019, the IC406 train on the Budapest - Warsaw route will take the Krakow - Warsaw route at 3:16 where it currently defeats at 2:47 and a year ago it defeated at 2:30. Why such an extension?
Same with TLK Branicki. A year ago he traveled around 2:30 on the Krakow - Warsaw route at 3:18. Good progress. Below is a comparison.
