One of the advertised bus links is that from Leuchars rail station to St Andrews in Fife, Scotland.
Bizarrely, it is possible on the Scotrail website to buy a London to St Andrews bus station Advance for a combination of an LNER service from London Kings X to Leuchars, plus the bus to St Andrews, but such a ticket is not available on the LNER website because (seemingly) St Andrews bus station is not included as a destination on the LNER journey planner.
