Well, that's odd. Metronet's chief executive appeared before the GLA's transport committee on Thursday afternoon. And a shedload of P-way work was called off without warning on Wednesday night. A coincidence? Surely not.
When Metronet protection masters tried to book on with the Track Access Controller, they were told that Metronet had withdrawn their SABRE job numbers without explanation. So only a few of the 30ish sites currently being worked on by TrackForce were active and hundreds of engineering workers were left with nothing to do.
