Here’s the conundrum I am grappling with today, concerning the Northern Line on the London Underground.
When you embark at London Bridge, the Northbound and Southbound lines are arranged in what I would describe as the Continental style. That is, to the right of each other. It is the left set of doors that open. However, when you disembark at Angel, the two lines are arranged in the Commonwealth style. That is, they are to the left of each other.
How is this possible? It must mean that the two lines twist around one another, like a double-helix. Either that, or we have some sort of Subway Named Mobius beneath London. Can anyone explain the peculiar engineering or physical geography that causes this to be the case?
I wonder, do maps of the actual underground network exist anywhere online? Not the Harry Beck maps, or its Google representation but a accurate scematic of the actual tracks, junctions and stations. I fancy it might be quite a fascinating labyrinth.
Every day thousands of travellers take the Eurostar to a strange and foreign land. No, not Paris; the Fourth Dimension. Although many visitors to Paris don’t realise it, at the heart of the city is a portal to hyperspace. As you emerge from the Paris subway into the financial district at La Défense you are greeted by a huge four-dimensional cube.
