I don’t see a 30 something minute connection as remotely efficient. They’re the epitome of operational convenience over service. Get two of those in a journey (before and after the core XC bit for example) and that’s an extra hour added to a journey that will likely struggle to beat the road equivalentAgain, that is a matter of what connections can be prioritised. If everything were able to run half hourly, almost all connections would be made within half an hour.
