Martin Bangratz has created a striking aerial map of the London Underground, using a photograph taken from a plane window to show how the network's lines actually intersect across the capital. The image, which colour-codes each Tube line, reveals a layout far more chaotic than the iconic, geographically simplified TfL map suggests.
A Creative Project Born from a Reddit Photo
The concept originated in 2018 when Bangratz came across a sweeping aerial photograph of London posted on Reddit. He sought and obtained permission from the photographer, known as @djsantero, to use the image as the backdrop for charting the Tube's complex routes. The result is a vivid visual depiction of how the lines weave through the city's neighbourhoods.
Bangratz's map includes the Overground, DLR, and Waterloo and City lines, leaving nothing out of his ambitious cartographic project. However, it was created before the Elizabeth line opened, which explains its notable absence from the map.
Reddit Users Point Out South London's Sparse Tube Coverage
Sharp-eyed Redditors were quick to identify a glaring omission in the map: the conspicuously sparse number of Tube stations across South London. One user remarked, "South London tube really needs expanding." Another agreed, saying, "Yeah, no wonder the Northern and Victoria lines are always rammed."
A Redditor offered a geological explanation for the disparity, explaining that north of the Thames lies a thick layer of clay, which is easy and safe to tunnel through. In contrast, the south has a very thin clay layer over waterlogged gravel, making tunnelling hard and dangerous.
Historical Context and Lasting Impact
Another commenter provided historical perspective, noting that South London was well-served by an extensive tram network during the time Tube construction was fashionable. This context helps explain why the Tube network developed unevenly across the city.
The map has sparked renewed discussion about the Tube's geographic accuracy and the challenges of expanding the network. While it is a creative visualisation, it underscores the real-world constraints that have shaped London's transport infrastructure.
