I noticed that Crossrail work has now started being blamed for weekend
Underground closures: "Between Edgware Road and Barking there is no
service due to Thameslink and Crossrail work.".

Perhaps this has been said before, but it's the first time I've noticed
it in the weekly TfL closures email. But I guess we'll have to get used
to seeing it many, many times more in the coming years.
