Re the Mayor and the name change of the Overground lines. There were six lines covering large parts of London, north, south, east and west. All had the same name. Imagine you're a tourist and you're told you need to get the Overground. Which part? Or the overground which is not the same as the Overground...? And every day I see notices about "Part Closure of the Overground". Which part? Is it the part I need? Rebranding means that they can say Part Closure of the Liberty Line or whatever and I don't need to worry. Basically it's a solution to a problem that was caused by expanding a network but not labelling it properly as they did so.
And the cost is tiny compared to the millions Johnson spaffed on water cannons that were illegal, the Garden Bridge that nobody wanted, the Routemaster buses that failed H&S, the pod travel across the river that nobody uses.... The man was a cash burning fool.
