After we've got to Olympia we will walk to Hammersmith – probably the longest walk we'll do all day. Hammersmith, like Edgware Road, Paddington and Shepherd's Bush, has two seperate stations on different lines, and they're all on this next segment which ends at Edgware Road.
Being 9 minutes late at Westminter, we popped out for the toilets, getting to Earl's Court in time for the subsequent Olympia train. We were lucky enough to get a bus from Olympia to Hammersmith, but we're still 16 mins late leaving Hammersmith.
