The only down side is that TfL generic service descriptors such as 'Good Service', 'Minor Delays' (etc) are totally misleading. I've had a 'Good Service' on the Bakerloo line whilst in reality the nearest train was 10 mins away (central section) with serve delays. The station controller was announcing a good service on all London Underground lines before doing a local announcement on the Bakerloo announcing the delays. That is the joy of having a central information controller. But hey, thats another can of worms!
BTW. Shouldn't this be in another area? FT&R doesn't quite fit
