    specify that fare class ""b"" is valid for travel between zones 3 and 4, and for travel between zones 3 and 5, the
    fare_rules.txt file would contain these records for the fare class:

    /** Identifies the zones that a rider will enter while using a given fare class. Used in some systems to calculate
    correct fare class. Example: If fare class ""c"" is associated with all travel on the GRT route that passes through
    zones 5, 6, and 7 the fare_rules.txt would contain these records:
     fare_id,route_id,...,contains_id
     c,GRT,...,5
    c,GRT,...,6
    c,GRT,...,7
     Because all contains_id zones must be matched for the fare to apply, an itinerary that passes through
        zones 5 and 6 but not zone 7 would not have fare class ""c"". For more detail,
