Not that it will ever happen given the level of technology present to prevent such an occurrence, but it is something that I’ve always wondered about. It’s also something that I wouldn’t mind seeing if they ever did test them… So any of you Safety or Railway Engineers out there, give me a call if you hear of anything!

I had another ‘inner Sheldon Cooper’ moment yesterday... At Covent Garden tube station I overheard a small child asking his mother why it was so windy in the underground tunnels. I resisted the temptation to launch into a full on explanation of the piston effect and how it also acts as a cooling mechanism for the underground, leading onto the issues surrounding keeping the temperature down throughout the entire tube network… Although I did have to bite my lips together quite hard to stop the words coming out..

Maybe I should go along to the IET Railway Network Young Professionals Quiz night on the 10th October where I’m sure to find some likeminded people?
While I’m on the subject of the London Underground, I’d really like one of these! Gives a whole new meaning to the phrase “Sound of the underground”.
