A while back, a certain Geoff Marshall started an unfounded rumour that it is faster to use the escalators to switch lines at Green Park tube station, than to use the corridor route suggested by TfL.
Then we got thinking: what if the rumour was actually true? Only one way to find out...
(We should point out that during peak/busy time it's always better to follow the official TfL signage in stations as overcrowding can be an issue)
