Delays occur occasionally, mainly due to demonstrators or minor incidents, and maintenance work on the network is done mostly during summers.

Tickets and passes allow free transfer and are universally valid on the Tramway, Busway, Nantes buses, Navibus, and suburban trains within Nantes Métropole.
