What caused this extra congestion? A bomb threat? Signal failure? No, London Underground has “decided to do its bit for the environment” by turning off “unnecessary” escalators to save energy.

The very same escalators that recently had their zero-watt poster slots replaced with dozens of energy-chomping LCD screens. Which lead down to the lobby containing another half dozen, six-foot LCD screens showing bigger versions of the same video adverts. Which leads to the platforms, with six newly-installed, ginormous projectors blasting video ads on to the platform walls.

If that’s London Underground “doing its bit”, Victoria’s going to be a seaside resort before we know it.
