This does all rather presume that Chiltern will keep stopping between

obliged to do so under the agreement with LU?

Part of the regulatory requirements at privatisation is that there is no
degradation of service from BR days - the Passenger Service Requirement
(IIRC, it was a long while ago!).

There are already two
(morning) up and one (evening) down Chiltern trains that don't stop at
Amersham - though I understand they do actually pass through slowly
(for a trip-cock test?).

Two up that don't stop at Amersham and two more that don't stop south of
Amersham. Similar on the return (neither the 18:23 nor the 19:15 ex
Marylebone stop at Amersham).

This could be taken as suggesting a
begrudging attitude by Chiltern in serving Met line stations, though
I'd think it's just a sensible approach with regards to busy peak time
services.

They were additional services added in the mid-1990s to cater for the
increasing number of commuters from north of Amersham, rather than a
withdrawal of stops from other services. The only station that lost its
Chiltern services was Moor Park.

Any idea which of the Amershams and Cheshams will be faster/slower?
Will they stop at Wembley Park etc?
