TubeWalker

TubeWalker began when a colleague decided to walk every connection on the London Underground, actually walking the routes between stations instead of taking trains. I built this Electron app to help him track his progress across the network. The app uses TfL's official station data and OpenStreetMap to display an interactive map of all tube stations and connections, letting you click on routes to mark them as complete. It tracks stats such as total distance walked, completion percentage, and progress by line.
