On Saturday evening, I had to go from Barbican to Amersham. There was no
Met service north of Harrow-on-the-Hill from which a bus was running at
the cost of an extra hour. The Journey Planner suggested taking the
Marylebone to Birmingham Snow Hill service to Beaconsfield and a Rail
Replacement Bus to Amersham. I found no information on the Chiltern
Railways site about the cost of this with a Pay as you Go Oystercard.
I saved about 30 minutes on this route. At Amersham, a ticket office
clerk confirmed that my ticket was valid on this route. I touched out
and was charged a plausible fare.
