The entire Circle line closed. Most of the Jubilee line closed (sorry Stanmore). An important chunk of the Central line closed (sorry Epping, sorry Hainault). The middle section of the District line closed (causing lengthy diversions for anyone trying to get from one side to the other). The entire Victoria line closed (first thing in the morning if not later). The entire Waterloo & City line closed (because it always is on a Sunday, although this particular Sunday it might be useful if it were open).
These track closures are particularly annoying if you're trying to get from the East End to the West End by tube. Want to travel from West Ham to Westminster? Normally one train, but this Sunday it'll be at least three. Want to travel from Woodford to Waterloo? Get on a bus. For many Londoners, this Sunday's not looking like fun at all.
But things are even worse than TfL's map shows. The entire Docklands Light Railway is also closed, every last bit of it (sorry Docklands). The Overground from Richmond to Stratford is closed, every last bit of it (sorry Hackney). The Overground from Barking to Gospel Oak is closed (doubly sorry Walthamstow). The Overground from Willesden to Shepherds Bush is also closed (sorry Westfield). And can we see these additional disruptions on the map, in order to get a complete picture of engineering-induced gridlock? No, sorry, not allowed.
And it's even worse than that, because there are also track closures on various National Rail lines in the capital. Victoria to Peckham, suspended. Stratford to Tottenham Hale suspended. More astonishingly, Southeastern trains through London Bridge will be diverted away from Charing Cross and will terminate instead at Cannon Street. This is despite the fact that Cannon Street has no tube service whatsoever on Sunday, and neither do any of the Circle line stations to either side.
London's rail network has more holes in it this Sunday than a chunk of Swiss cheese. And is there a map anywhere which shows how all these slices of disruption fit together? No there isn't. Tube, DLR, Overground and Rail all display their line closure information in unhelpful segmented silos. No rail company or higher authority provides a complete engineering overview because it's nobody's responsibility to do so. Joined-up thinking isn't legislated for, so it doesn't happen. In the meantime the travelling public are left to try to work out how to manoeuvre round the gaps, even though not all of the gaps are obvious. Come on, somebody, somewhere, do London a service and provide us with the big picture. Every weekend. And especially this weekend.
