Can't remember where I read it but AIUI yes - there will be a full
peak hour Bakerloo Service north of Oueens Park. Queens Park will
provide
flexibility to stable offpeak and enable short turn back runs to meet
inner London traffic requirements - ala Willesden Green/ Whitecity/
Liverpool Street etc. Again new stock on the Bakerloo will be
necessary to effect the change.

Which is what the old Victoria Line stock will be used for. It all
makes sense, really. It's just going to take a bit of time.
