“We all know that booking international rail tickets can be quite difficult, but how big is the problem?” That was the question that Thomas Preslmayr and students of the Austrian St. Pölten University of Applied Sciences set out to answer with an empirical study. And the result was striking: the rate of failed bookings for trains was 10 times higher than for flights, out of 304 bookings. At RailTech Europe, Preslmayr gave a presentation about the study.
