We're counting down the least used stations line by line on the London Underground, this time to the Piccadilly and the delight that i North Ealing.
You can download the Entry & Exit figures for all Tube Stations here: https://tfl.gov.uk/corporate/publications-and-reports/underground-services-performance (although, it will obviously spoil the series for you if you look ahead at the figures!)
Note: The Waterloo & City Line won't be done, as it's only two two stations and it's figures are ridiculously high, because the stations are Waterloo and Bank.
There's scope though to do 'Least Used...' on the Overground, DLR and Trams.
