When it comes to train travel, there is one major player in Poland - the company called PKP Intercity which is also a national carrier. Unfortunately, I don't know anyone who see no flaws in PKP Intercity website and use it effortlessly. But I know a lot of people in all ages who'd rather go to the station and buy a ticket face-to-face only to avoid using this site. As it is carrier supported by the government, it should be user friendly, so… what exactly goes wrong? This is always a tough question.
