Here are the scheduled Tube system repairs for this weekend.
Most of the closures are outside of zone 1. The exceptions are parts of the Circle line between Kings Cross and Moorgate and a section of Hammersmith/City over by Liverpool St station. Once again, the text doesn’t match the map, so double-check. London Overground and DLR, Bakerloo, Central and Northern lines all have disruptions outside zone 1.
Since I use the Tube so much when I’m in London, I like to know this stuff even if I’m not gonna be there. This weekend, though, I DO need to know and I am staying at a hotel just one block from Paddington station which allows me to get to shopping and theatres as well as not needing the Tube should I choose to get to Heathrow via the all-too-expensive 15-minute Heathrow Express.
