They are valid only in buses. Stamping a ticket of 1.30 PLN you can travel the distance of 10 bus stops. Stamping a ticket of 2.30 PLN you can travel any number of stops until the last one of the bus line taken. You can not change the bus during the trip when using this kind of a ticket. However, the stops-limited tickets are not being sold as widely as the time tickets.
Many kiosks sell only the latter.
Two reduced rate tickets are not valid as a full rate one. You should pay a full rate fare for each piece of luggage exceeding 65x45x25 cm. Leaving the station through the main door you walk some 300 m straight ahead, up the Dworcowa Street. We recommend the map of the centre of Poznan available at our WWW page. At the beginning of July the temperatures may range from 15 to over 30 C. Be prepared for any case and do not forget your umbrella.
