Between Gdynia and Kaliningrad there is train with direct car Berlin - Kaliningrad, running from late May till early October. I'm planning a tour of Poland, and now I'm considering adding Berlin and Kaliningrad to the tour. So I will buy return ticket Bratislava - Hel with outward route via <1156>Kuty(Gr)<1154>Brno*Ceska Trebova*Letohrad*Lichkov(Gr)<1251>Wroclaw*Poznan*Tczew*Gdynia Gl, and return route via <1251>Gdynia Gl.*Dzialdowo*Warszawa*Idzikowice*Krakow*Trzebinia*Oswiecim*Zebrzydowice(Gr)<1154>Bohumin*Prerov*(Hodonin/Brno)*Breclav*Kuty(Gr)<1156>. According to Jizdenka that ticket should cost 84 EUR.
So according to this I plan to go first to Wroclaw, and then to Poznan, from were I'll go to Berlin with 19 EUR discounted ticket. Then I plan to use Berlin - Kaliningrad sleeper. Since I already have ticket for Poznan - Tczew part (ticket Bratislava - Hell) I'll need to buy Berlin - Poznan and Tczew - Kaliningrad tickets only and Berlin - Kaliningrad reservation. Then I plan to go from Kaliningrad to Gdansk, for which I will use Kaliningrad - Tczew ticket, and then from Tczew to Gdansk continue using my Bratislava - Hel ticket.
So I need information how much is the cost of:
1) Berlin - Poznan standard fare ticket (TCV) (is there youth, or RailPlus discount?)
2) Tczew - Kaliningrad return ticket
3) T3 reservation Berlin - Kaliningrad
4) T3 reservation Kaliningrad - Gdansk
Thank you!
