The Cogne-Acquefredde (Plan Plaz) railway is a former mining infra¬structure, which has not been in service for over 40 years. In the 1990s it was modernized to reopen it for train traffic and to contribute to the tourist development of one of the most important Italian Alpine resorts. The results, however, were unsuccessful since, in addition to technical errors showed during testing, the project did not take into account its inadequacy to support the expected traffic flows. It was a typical case in which applied cartography would have solved posi¬tively a problem that was not taken into consideration from an engi-neering point of view.
The graphic time-table, a particular kind of two-dimensional car¬togram, with a space-time development, is considered in this work to highlight not only its possible theoretical field of application in a railway with a tourist value, but also the role that the geographer can have, alongside the transport engineer, in the project of a transport infrastructure.
