The route
What the journey 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 203 km against 194 km in a straight line, a detour of 5 percent. Track and road geometry account for the difference.
- Where the change is
- Connections are made at Weston-super-Mare, Newport, Bristol, Cardiff. The gap between arriving and leaving is 50 minutes, of which about 14 is walking.
- If the connection is missed
- The tightest connection we sell here has a 19 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.

Where these numbers come from
Places, coordinates, operators, which operator serves which pair, and every distance on this page are real and come from open data. Where a corridor has a filed timetable the departure times are real too, and ferry fares are the prices the operators publish themselves.
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.
Where no operator publishes a fare for a corridor, the price here is our own estimate, worked out from the real distance and the real operator through a fare curve that follows lead time, day of the week and season. It tells you roughly what the journey costs. It is not a seat anyone has agreed to sell, and the payment step will not take it.
