gurgled happily, sounding much like they were
saying:

Just been reading on Wikipedia that Amersham might be going down to
having just two trains an hour? Is that not a really poor service?

Not really, because you can use the Chiltern Service. The last time I
was on an Amersham train during the day, it wasn't very full.

Out of interest how much does a single from Amersham to Zone 1 cost?

£5.50 daytime Oyster, £8.20 off-peak ODTC, £15 peak ODTC.
