The time frame of a ticket is determined by the Railroad Company that is the owner of the train for which a specific ticket was bought.
For example – a one time ticket for a POLREGIO (Przewozy Regionalne) Company has the following time frames:
– for a distance no longer then 50 km – 3 hours valid from the hour specified on the ticket (ważny od – in polish that means valid from)
– for a distance between 51 and 100 km – 6 hours valid from the hour specified on the ticket (ważny od – in polish that means valid from)
– for a distance longer then 101 km – 1 day starting at 0:01 and valid until 24:00
The same rule is repeated by most of the regional Railroad Companies.
Information specifying the time frame of a ticket bought through KOLEO can be found on that ticket in its PDF version or when viewing that ticket on KOLEO website or via an application.
In regards to the PKP Intercity a one time ticket will be valid only for use on board one specific train. It will also have a time frame but that time frame will simply be made by the hour of departure and hour of arrival of that one train.
