Let’s make this simple, shall we? If you’re out late on a Friday or Saturday, the Piccadilly Line runs all night between Cockfosters and Heathrow (Terminals 1-3). If it’s any other day, the trains tuck themselves in by 1 a.m. The branches? Forget about them—they’re like the cousins who leave the party early to “feed the cat.”
Also, remember: the Night Tube on the Piccadilly runs every 10-20 minutes, so you won’t be waiting forever. But don’t expect a throne—these trains are not empty. You might share your carriage with a group of tourists arguing about the best fish and chips, or a sleepy airport worker who’s mastered the art of napping standing up. It’s all part of the charm.
