Yes, but the Bakerloo trains cannot be blamed for making Silverlink Metro
trains late arriving at Hatch End from Watford. Are the schedules just
unworkable, the trains incapable of maintaining the timings ?

Of course they can. If the Bakerloo is in such disarray as to cause
Watford-bound services to be significantly late on the outward journey then
they will quite likely be late on their return, making them late slotting in
between Bakerloo services from Queens Park and making them even later on
their London-bound journey. However much recovery time is built in at the
terminii for turning trains back can easily be used up if the Bakerloo
section is completely SNAFU'd and delays can accumulate throughout the day.
