this Please note the following for travel arrangements!
Please note that the Circle Line and District Line are either cancelled or not running a full service this weekend, making it a tad difficult to get to Blackfriars. One option is to go to Embankment and walk from there, or get a bus. Another option is to go to Liverpool Street Train Station, and taking the 100 Bus, travelling towards Elephant & Castle
