How late are we running?
ri-TAR-do — stress on second syllable. SIA-mo — stress on first syllable.
During the journey when the train has slowed or stopped unexpectedly and you suspect a delay.
'Siamo in ritardo' (we are late) + 'di quanto?' (by how much?). The combined question is 'siamo in ritardo di quanto?'. On Italian trains the display screen usually shows the current delay. If not, the inspector or fellow passengers can often tell you.
Il treno è fermo da dieci minuti — c'è un problema?
The train has been stopped for ten minutes — is there a problem?
Ask when the train stops unexpectedly
Ho una coincidenza — sono preoccupato per il ritardo.
I have a connection — I'm worried about the delay.
Express your concern to the inspector
Quando prevede di arrivare a Roma?
When do you expect to arrive in Rome?
Ask for an updated arrival estimate
Train delays in Italy are announced on the on-board display and by the driver. Passengers are entitled to compensation for delays over 60 minutes on high-speed trains. Regional train delays are less consistently compensated. The Trenitalia app gives real-time train position and delay information — useful for planning connections.
