The Tutorial Route (SETR) was initially built as a companion to the Scenario Editor Tutorial, developed by Wilbur Graphics. In this role the SETR will also be used in future tutorials. The route represents a fictitious NS line, flexibly situated in the time around 1990, when the railway infrastructure is characterized by concrete ties and daylight signals. All tracks have been equipped with catenary. The surrounding landscape and urban buildings have been developed as credibly as possible. The effective driving length is approx. 23 km.
