London's iconic underground train map will be rebranded

LONDON -- For anyone with even a passing acquaintance with London, the city's Tube map is as iconic as the red buses or the black cabs.

But for the past few years, there's been something not quite right about the map originally designed by Harry Beck in 1933 — a collection of orange train lines, mostly orbiting the city, known as the London Overground.

They are like an interloper on the carefully crafted and easy-to-navigate map.

Yes, it's been confusing for Londoners too.

Now, London Mayor Sadiq Khan hopes to bring some clarity to the suburban rail network that was established in 2007 through the effective merger of previous routes, and has grown to carry more than 3 million customers a week across more than 100 miles (160 kilometers) of railway and 113 stations.
