a large part of the passenger volume on interurban routes is accounted for by passengers who begin or end their journeys on rural routes

within the last two decades several of the least used rural routes have been closed and their passenger services have been replaced by buses

the rural routes were all originally constructed at least one hundred years ago, whereas some of the interurban routes were constructed recently for new high-speed express trains

not all of Appenia's large cities are equally well served by interurban railroad services

the greatest passenger volume, relative to the routes' capacity, is not on either category of long-distance routes but is on suburban commuter routes
