Last week, wracked by neck pain, the only thing I could do was sit on a couch and count Tube stations. Damjan had said that he thought there were around 200. This, in my opinion, was a gross overestimate.

To prove it, I got out an Underground map and started crossing them off. I took bets. My vote was for 112 stations. Neo guessed 100. Damian was more ambitious at 140.

I took a broad view of what a ‘station’ was. Anything on the Tube map was fair game, so I ended up counting stations on the Overground and Docklands Light Rail, as well as those on the temporarily closed East London line. I excluded the recently decomissioned Shoreditch station and included the new station at Heathrow Terminal 5.

Very quickly, the tally steamed past our paltry estimates. Even Damjan’s ‘gross overestimate’ was left in the dust trail of my black pen, as shown below.

The answer is… 344! To me it seems like a massive number. Who would have thought?
