Here are this weekend’s Tube closures. The biggest disruption in central London is the Central Line closure, extending east beginning at Marble Arch.

Partial closures on the Bakerloo, Metropolitan and Northern lines are also scheduled, as well as some Overground, Tramlink and Docklands service.

Here is a link to the Planned Works calendar through mid-July, when all Tube line maintenance will be suspended for the Olympics weeks, save on the Waterloo and City line. In theory, at any rate.
