The TAN network includes three modern tram lines that intersect at the Gare Centrale (Commerce), the main bus/tram transfer point. Buses run from 6.45am to 10pm. Night services continue until 12.30am. Bus/tram tickets (€1.50) can be individually purchased from bus (but not tram) drivers and at tram-stop ticket machines. They’re valid for one hour after being time-stamped.
