Yesterday morning, the job really did go right up the wall.
We reported just a few weeks back about lumps of concrete falling onto tracks and endangering life and limb. That time, it was on the Central Line, this time it's the Met/H&C.
The falling rock fouled the juice rails and the running rails, and it was only the alertness of a track workers that prevented a potentially-disastrous derailment.
With Kings Cross - and, at one point, Euston - closed, there was the inevitable knock-on effect on other stations, with Bank also closing due to congestion from passengers taking alternative routes.
There is good reason to believe that the spate of dodgy concrete is a hangover from the PPP days - a hangover that is going on longer than it should because of continuing widespread contracting-out and profiteering. This incident allows illustrates the folly of even considering cutting staffing levels - whether on the track, on the stations, or elsewhere.
