Over the past year, Londonist video maker Geoff Marshall and developer Matthew Frost have been quietly working away on a rather special project. Their Station Master app is already one of the best guides for getting around the capital, drilling down to such detail that it even tells you which train doors to use for the quickest interchange at any tube station. But it's just been updated with a unique feature: three-dimensional maps of the tunnels, escalators, tracks, exits, lifts and concourses of every Zone 1 station, and some beyond.
The plans are not only fascinating in their own right, but also a helpful means to finding underground shortcuts, or a cunning lift or stairwell that can get you to the concourse quicker than the escalators. The maps are particularly helpful for those with special accessibility needs — you can check in advance which routes through the station have fewest steps, or where the lifts are.
Station Master takes tube geekery to a new level, maps that level, and shows you where the exits are.
Available now for Apple devices for just £1.99. Go get it now.
Note: all station maps are available in high resolution within the app, higher than shown here.
