It's easy to find out what the busiest and least busiest stations in the UK are, the latter even more so thanks to Geoff Marshall's All The Stations YouTube channel. With most of the rail community aware of annual passenger figures, it would be more interesting to find out if there are any stations on the national rail network that have received zero ticket sales to a certain other station. I'm sure there are bound to be a fair few, such as somewhere on the Cornish branch lines to a remote station in the Scottish Highlands, or a journey between two of the quietest stations such as Shippea Hill to Redcar British Steel.
