The easiest way to solve the problem would be to adopt a LOROL style
approach to ALL suburban services in London, whereby the service
frequency and operations are determined by TfL and operated under
contract by the respective TOCs.


But wouldn't that effectively mean that almost the entire rail network in
the south-east would be decided by TfL - a body controlled by the mayor of
just part of that network?

Most south-east services are to, from, through London.
