4LM Delayed

The "Four Lines Modernisation" (4LM) upgrade on the District, Met, Circle, and H and C missed the 17/18 November "go live" date for the first phase of automatic train operation.

There have been numerous problems with Thales' new signalling system, including more than one train entering a signalling section at once during a simulated test. It has now been put back to next year. By 2018, Bombardier was supposed to complete the entire upgrade - before it pulled out of its contract, costing TfL £85 million. Thales doesn't seem to be seem to be delivering on its promises either.
