Ever wondered, with your nose pressed into someone’s clammy, mid-commute armpit, exactly how many Londoners do the same tube journey as you? Ponder no more – there’s now a nifty tool to find out how many people take your Underground route each day.

All that swiping in and out means TfL gathers loads of data about people’s journeys. And its number-crunchers can put it to good use to improve services, but it’s also handy to build sparky, curiosity-satisfying little widgets like this.

All you have to do is enter your departure and destination stations to measure how many fellow commuters do your daily grind. For example, each day 254 Londoners take the tube from Covent Garden to Leicester Square – a meagre seven-minute walk (five if you’re in a rush). We reckon it’s either because they missed their stop, or want to avoid Covent Garden station’s thigh-crushing 193 steps.

Above-grounders will be able to crunch the figures soon too, as the engine is rolled out across the DLR and Overground. With a little bit of luck, this mathematical mood enhancer might make you feel that little bit closer to your public transport companions – spiritually, at least. No one wants to get closer to those armpits.
