We arrived in Sestokai to find a Lithuanian train waiting across the platform, headed to Kaunas. As it was about to leave, there was no time to run to the ticket office to buy a ticket. I asked a conductor and he said to get on the train and buy the ticket there. I did this with some trepidation, having heard of problems. However, I asked another conductor, who gladly sold me a ticket to Kaunas for 10 Litu. I would recommend to travellers prepare themselves by bringing about 20 or 30 Litu with them from Poland, so they can buy an onward ticket; I wouldn’t want to have to looked for a currency exchange office in Sestokai.
