There are placards in tube stations, listing lines and segments of lines that will not be operating this coming weekend, September 1 and 2:
- Circle Line
- District Line between Edgware Rd and High Street Kensington
- Hammersmith and City Line between Moorgate and Hammersmith
- Metropolitan Line between Aldgate and Wembley Park
There may also be something going on with the Bakerloo Line. It's listed in the online Works Calendar, but I didn't see it mentioned on the notice in the station.
