Warsaw->Pardubice(cz).

If I take the train in Warsaw centralna, 09.25,then I am on 16.39 in pardubice. Even I can take a train earlier(and change in bohumin). For this train(110Praha) I can use a 'Sporoticket',quite cheap. But where can I book and buy it online? Just buy the sporoticket warsaw-prague-(warsaw) and get off in Pardubice.

The "Sporoticket" is an offer of Czech Railways and is valid only for itineraries originating in the Czech Republic. Prague - Warsaw - Prague can be done with a Sporoticket, but Warsaw - Prague - Warsaw cannot (there is a requirement by the Czech Railways that the Warsaw - Prague Sporoticket to be valid must be stamped by a Czech train attendant during the Prague - Warsaw journey).

The Polish railway company that runs international trains is PKP Intercity, www.intericty.pl. Unfortunately, apart from Warsaw - Berlin, they don't sell international tickets online.

A regular Warszawa - Pardubice ticket bought in Warsaw costs ca. 45 euros. Return is 20-30% cheaper than 2 singles. There is a limited number of special SparDay tickets available for 19 or 29 euro (they are issued only for the whole Warsaw - Prague route, but there's no problem with getting off the train earlier). They can be bought no later than 3 days before departure. They are only available at ticket counters (any international ticket office in Poland) and might sell out before you arrive in Poland. If those tickets are sold out, your cheapest train option (apart from connections using regional trains that take 12+ hours) is the regular Warsaw - Pardubice ticket for 45 euros and a Czech Sporoticket for the return leg.

There are no sensible daytime bus connections from Warsaw to Prague - the train is much faster on that route.

Ten years ago, I needed to go from Warsaw to Trutnov cheaply. Like Pardubice, Trutnov is about 20km from Kudowa Zdroj. I took the overnight train to KD (cheap) and cycled across the border (it's not far for walking) and then biked to Trutnov (you can probably take a bus from there).

Not sure if the train still goes there but it's worth looking into. From the border to Pardubice is only about 20km.

Given the very cheap overnight bus from Warsaw to Prague (polskibus.com), the route mentioned by #3 makes little sense nowadays, both cost- and timewise, especially that the trains to Kudowa Zdrój have been cancelled.

Thanks folks for all the very usefull information... But "unfortunately".... won't go to pardubice(some friends are working and can't attend the game) and stay in poland(4 days warsaw, 2 days Poznan.

If somebody have usefull info to get from Poznan immediately to Warsaw Modlin Airport.... ?

You'll need to pass through the center of Warsaw anyway. Take either the train (faster) or bus (cheaper) to Warsaw and then use local train to Modlin and a shuttle bus to the airport or use the direct bus from Warsaw Central Railway station.

Yes, like I supposed I have to go to Warsaw and then look for a connection to Modlinairport.
Thanks Igor!
