We contributed to the architecture design, the implementation of selected user-interface modules for issuing travel documents, the synchronization service, the printing of the travel documents themselves on an external printer, and reporting. In recent years, we have jointly implemented new modules for train delays, violations of transport regulations, photographic evidence, crew roster planning, assignment of ticket inspections to inspectors, issuing reservations and displaying a train’s reservation status, and ticket distribution for account-based ticketing.
