Tube Icon Undergoing Change

Yesterday, I got an email from Transport for London informing me that the overland train lines known as the Silverlink Metro are now going to be known starting next week as the "London Overground." Not a big deal, but the overground routes will be included in the iconic Tube map starting next week. Annie Mole has a sneak preview of the new map. She says it looks crowded. I think it looks like a stone of potatoes in a half-stone sack.
