Such a provisional solution would be needed only if the trans-European HS line were to be delayed beyond 2015, in which case Poland should muster enough courage and money to initiate its construction over the roughly 100 km between the Warsaw junction and the outskirts of Łódź, on the way to Poznań and Berlin.
On its way to Warsaw, the future trans-European railway could join, with another pair of tracks, the existing PoznańŁowiczWarsaw (E20) line west of Błonie, with some adjustments for the tight curves of the old line.
The interim solution (old lines branching off to Airport) would result in travelling times of 20 min. from Warsaw and 40 min. from Lodz. With the direct HS line from Warsaw to Łódź, these times would be cut to 12 min. and 27 min., respectively. Once turned into a high-speed line and suitably upgraded over its final stretches, CMK would bring Katowice and Cracow within 55 min. of the Airport station. The same running time could be obtained for Poznań, once the trans-European railway comes close to that city.
