the bit most guides get wrong
Transfers are free — with rules
Fares are charged on the total distance travelled in one journey, regardless of mode and whether direct or with transfers.
15 min train to train
45 min train to bus, or bus to bus
5 transfers per journey, maximum
2 hr total journey length, maximum
two rules that catch people out The next bus service must differ in number from the preceding one; no exit and re-entry at the same train station.
Transfers to or from non-public buses - premium, shuttle, temporary, special, privately operated cross-border and tourist buses - do not qualify as valid transfers.
A private shuttle fare is paid on top of the public fare AND ends the fare journey, so a following public leg starts a fresh journey at the first band. This is why a flat-fare shuttle can cost more overall than a longer public bus ride.
