The route
What the journey actually looks like
Direct or connecting, how far the route really runs, and what happens when a connection is missed.
- Direct or connecting
- 20% of the services we sell on this corridor run through without a change. The remaining 80% involve one connection.
- How far it really runs
- The route covers 726 km against 631 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 Quarto Oggiaro, Milan, Brescia, Verona. The gap between arriving and leaving is 51 minutes, of which about 14 is walking.
- If the connection is missed
- The tightest connection we sell here has a 18 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 Grenoble at 06:31 and the last at 07:30, across 5 departures. The return direction keeps its own timetable, so the times back are not these times reversed.

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.
