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
- 33% of the services we sell on this corridor run through without a change. The remaining 67% involve one connection.
- How far it really runs
- The route covers 580 km against 563 km in a straight line, a detour of 3 percent. Track and road geometry account for the difference.
- Where the change is
- Connections are made at London, Nantes. The gap between arriving and leaving is 47 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 Dublin at 06:46 and the last at 07:30, across 3 departures. The return direction keeps its own timetable, so the times back are not these times reversed.
