- Direct or connecting
- 50% of the services we sell on this corridor run through without a change. The remaining 50% involve one connection.
- How far it really runs
- The route covers 494 km against 430 km in a straight line, a detour of 15 percent. Track and road geometry account for the difference.
- Where the change is
- Connections are made at Rimini, Ancona, Perugia, Terni. The gap between arriving and leaving is 45 minutes, of which about 5 is walking.
- If the connection is missed
- The tightest connection we sell here has a 20 percent chance of not being made on the timetable alone. Part of this journey is a self transfer between separate tickets, so leave more time than the minimum and expect to check in again.
- First and last departure
- The first service of the day leaves Rome at 06:02 and the last at 06:50, across 2 departures. The return direction keeps its own timetable, so the times back are not these times reversed.

What is provided on board the Coach from Rome to Trieste?
Operators on the Coach from Rome to Trieste publish Power outlets, Restrooms, Wi-Fi. That is what 2 carriers on this corridor state about their own fleets, across a journey of 7h 50m door to door. Where a carrier publishes nothing, this page lists nothing for it.
Where these numbers come from
Derived from service area No carrier record names this exact pair. The operators listed publish a service area covering both places at a distance their mode plausibly carries people, which is evidence that the corridor is served and not evidence of a specific service. Pages state which, because presenting the two as the same thing would be dishonest.
Schedules, seat counts and fares are generated by our own model until the supplier contracts are signed. Places, coordinates, operators, which operator serves which pair, and every distance are real. We would rather say that on every page than let a modeled number pass for a filed one.
