London Underground
London Underground (aka the tube) is a slightly sweaty yet essential way of navigating the city. Trains run along 11 lines, split into nine zones. Confusingly, what you pay depends on distance, time and which ticket you buy. Try to avoid messing around with pricey travelcards and opt for an Oyster card or use contactless payment instead. You’ll skip the queues and save money. Win-win.
