Does this line go through the station?
'Linea' — 'LI-ne-a', three syllables. Do not merge into two syllables as in English 'liner'.
Use at any bus stop when you need to reach the railway station and want to confirm the route. Replace 'la stazione' with any other landmark.
'Linea' refers to the bus route/line. 'Passa per' means 'passes through' and implies the bus calls at that stop without necessarily terminating there. It is the most natural Italian phrasing for asking about intermediate stops.
Questa linea va in aeroporto?
Does this line go to the airport?
Swap destination to airport — very common tourist question.
C'è un autobus diretto alla stazione?
Is there a direct bus to the station?
'Diretto' means no changes required.
Devo cambiare per arrivare alla stazione?
Do I need to change to get to the station?
Asks about connections when a direct bus is uncertain.
Italian bus route maps are not always posted at every stop. The city transport authority website or apps like Google Maps / Moovit are the most reliable sources for route information.
