A question about timetables and track capacity.
The current TfL Rail West timetable published on the TfL website, which I assume was developed before the Covid crisis, has a minimum separation between trains arriving at Paddington in the morning peak of 6 minutes.
I'm just wondering what the constraints were that made that decision.
The future plans for Elizabeth line service will need the separation to be 5 minutes to get 12 tph.
Is the only capacity constraint the lines into the station or are there others? Is the current TPWS/AWS signalling a constraint? If so, will it be fixed by the ETCS overlay that is being installed? I can't see how myself but maybe there are other changes being made too.
My thoughts were triggered by a couple of things. One was some suggested changes when Old Oak Common opens that more trains could continue to OOC and turn there instead of on the current turnbacks and the other being the possible plan for a North Kensington Station.
Is there line capacity on the Relief Line between the Westbourne Park Portal and OOC to allow more than 12tph? Would there have to be track changes to allow it? Is anything like that planned already for the HS2 OOC station build?

Crossrail opening delayed (opening date not yet known)
Crossrail was a hands off project. Both its equal cosponsors thought it was a good idea at the time. Not sure what hand the then Mayor had in it, but I’m sure the person with the current purse strings could offer some explanation with the further bailout.
