London's iconic Tube map is receiving a substantial update with the London Overground network undergoing a renaming and rebranding effort.

The six branches of the 113-station Overground will sport new names and colors, moving away from the uniform orange-bordered lines.

New line names—Lioness, Windrush, Suffragette, Weaver, Liberty, and Mildmay—reflect various facets of London's history and cultural heritage.

Rebranding has sparked mixed reactions, with some celebrating the cultural recognition while others criticize it for 'virtue signaling' and unnecessary politicization.

The renaming process involved consultations with diverse groups including customers, stakeholders, historians, and local communities, though it still surprised many residents.

Transport for London aims to simplify navigation of the Overground network with the rebrand, facilitating journey planning and clarity during service disruptions.

Despite controversy, TfL contends that the new line names will enhance the experience for users of the Overground, which is the second busiest railway in the UK.
