Westminster possesses one of the most extensive and densely connected public transportation networks in the world, overseen largely by Transport for London (TfL). Four major railway termini are located within the borough: Paddington, Victoria, Marylebone, and Charing Cross, providing vital connections to the rest of the UK and direct links to major airports (such as the Heathrow Express from Paddington).
The London Underground (the "Tube") heavily services the borough, with numerous lines—including the Bakerloo, Central, Circle, District, Jubilee, Piccadilly, and Victoria lines—crisscrossing beneath its streets. The newly opened Elizabeth Line has further revolutionized transit, offering high-speed connections east and west.
Above ground, Westminster is served by a vast network of iconic red double-decker buses. Active travel is heavily promoted, with an increasing number of dedicated cycleways (such as the East-West Cycle Superhighway) and pedestrianized zones. River boat services also operate from piers along the Thames, including Westminster Pier and Embankment Pier.
