I'm in Brentwood at the moment, all hotels in East London being full of overnighters. But I have a late-morning meeting near Euston, for which the Railplanner suggests the North London side of the Overground. Can I complete the whole circuit? Amusing as that might be, the idea of enduring SWT▸ from Clapham Junction back to Reading puts me off.
You could always try the other NLL branch to Richmond and pick up an SWT there - likely to be just as busy though...
I got to Brentwood on the Tuesday by going back to Shadwell and completing the east side of the Overground 'box' to Canonbury, then by Overground to Stratford.
Retraced my steps on the Wednesday, taking the Overground from Stratford to Camden Road and a bus from there to Euston. Alas the one I caught was an ordinary service bus - when I got off I found that the one that was behind was a hired-in Routemaster.
By the time the meeting finished, the idea of doing the whole circuit seemed entertaining. I'd hit the gap in the Cotswold line departures, so I'd have time to catch the 14:15 from Camden Road to Richmond as Paul suggested (and as the RailPlanner proposed) and get to Reading in time to catch the 15:52 from Paddington.
But ... the Overground was suspended between Willesden and Richmond on account of a point failure at Acton. So I end up having to do the Clapham Junction link after all - but this means that the connections don't work, so I was on the halts train out of Oxford instead.
The West London side of the Overground was full-and-standing but there wasn't anything obvious in the way of marshalling of passengers. Homeward journeys in the afternoon are probably more spread out in terms of time, so easier to manage.
So, there we are - a full circumnavigation of the Overground in response to the
LUL▸ strike.
