In a major rebrand, London’s six (previously all orange) Overground lines have been given new names and new colours to reflect the identity of the neighbourhoods they run through (and make the system easier to navigate). It’s also a way to celebrate the capital’s diverse communities and histories. For those wishing to explore further, I have walked six routes using stations on each line which take in dozens of landmarks with connections to the themes, from gardens and galleries to historic houses and monuments.
