Is it only me who thinks this, but maybe London ‘Underground’, should change. Something more like the DLR line within the underground would be much better, one for the tourism, but two… the most importantly, because there is air all around you, you can see the sun and the city landscapes, this feel’s much better than spending ages on a dirty tube stuck in some mucky tunnel about 10ft wide. I’m sure somewhere in Asia, have overground more than underground, trains flying through the air. Underground sucks in the sun
