| M13 | Napoli/Piazza Carlo III -- Aversa | 1967 | Service on this route has been suspended since 1997 or 1998. An extension from Aversa to Teverola is under construction, and reopening of the route (probably with a new/different route number) is definitely planned -- but not before 2002. |
| M13B | Short turn of the above. | ||
| M15 | Napoli/Piazza Carlo III -- Secondigliano (Rione 167) | 196- | A long (by European standards) suburban route (about 8 km). Service is rather infrequent and sporadic. Motorbuses are not substituted when the trolleybuses are not running. Route M15 simply does not operate at such times. |
