I was thinking of putting this in the London Underground forum but it's actually quite a useful bit of info which may not be fully publicised there, and it also may be useful for those connecting through London stations. You can use the TFL website but you may not have access to the latter when you need to estimate a journey length !

Anyway, back in 2002 I missed my train home because I'd misjudged how long it took to get from one side of London to the other on the Underground. So, I thought, there must be some way of estimating how long a journey will take, so over the next 20 or so trips I travelled I timed them and came up with the following simple formula. It's easy to remember and reasonably accurate, timings are from entering the station to leaving it,

The exact average was actually 2 minutes 17 seconds per stop, but 2.5 minutes is easier to remember......

I hope it means you won't be late for

*i.e. they include having to get down to the platforms, average waiting time for a train, and the getting back up to street level and out again*.**7 minutes plus 2.5minutes per stop (plus 5 minutes per change if relevant).**The exact average was actually 2 minutes 17 seconds per stop, but 2.5 minutes is easier to remember......
