What rail passengers need
A passenger choosing a train needs schedules, real availability, an understanding of what each class actually provides, and a seat they will accept sitting in for several hours. Popular routes sell out well ahead, so availability is the deciding factor. Foreign travellers add another problem: they cannot navigate the official systems and pay agencies substantially more than the ticket for the help.
What we build for a ticketing service
First, schedule search with live availability by class, since sold-out popular routes make availability the primary question. Second, class differences explained with photographs, because passengers currently guess and complain afterwards. Third, seat selection where the carrier permits it, which is what a long journey is actually chosen on. Fourth, combined journey planning with transfers and multilingual booking, since foreign travellers are the segment willing to pay a service fee for a process they cannot manage alone.
