Not quite as bad as Tuesday where I had seven hours of back-to-back meetings, plus traveling from Soho (the first), out to Canary Wharf (second & third) and back again for the rest. For the record, that would be the Bakerloo, Northern & Jubilee Lines.
I am currently sat on a Chiltern Railways train that runs non-stop from Princes Risborough to London Marylebone. It started at Warwick Parkway at 0540.
Everyone who got in the back carriage at the last stop got a seat. There are no empty seats.
That takes very good planning. Oh, and luck.
