That was my understanding of the reply that I received - the enquiry is to start late September/early October (presumably 2017). Of course, subsequent to the enquiry there's the possibility of various stages of appeal before work can actually legally start. Hopefully the project won't face a similar situation as to that which delayed the start of the Ordsall Chord project in Manchester, although I do understand the need for 'due process' with projects of this nature. And, all this assumes that Network Rail has the funding to do the work, presumably in CP6.
