About the Piccadilly line
Opened in 1906, the line serves the largest concentration of tourist attractions on the network: the British Museum (Russell Square), Covent Garden, Trafalgar Square (Leicester Square / Piccadilly Circus), Knightsbridge (Harrods) and South Kensington (V&A, Natural History, Science Museum).
Heathrow is served by a loop: Terminals 2 & 3 → Terminal 4 → Terminals 2 & 3 → Terminal 5. Make sure your train shows the right terminus.
Night Tube runs Friday and Saturday nights between Cockfosters and Heathrow Terminal 5 (via Terminals 2 & 3 — no Terminal 4 at night).
