The Tube's busiest day EVER: Can you guess how many MILLIONS of customer journeys were made on 9 October?

Highest number of customer journeys in London Underground’s 152-year-old history.

A grand total of 4,735,000 customer journeys were made on 9 October, the highest record in London Underground’s 152-year-old history.

The previous record was reached on Friday 28 November 2014, when 4,734,000 passengers travelled on the Tube.

The last week of October this year was the busiest ever week, with 28,614,000 journeys.

London Underground served 970 million customer journeys in 2001. This has risen 34% to 1.3 billion in 2014/15 with the rate of growth increasing in recent years

Nick Brown, LU’s managing director, said: “The Tube is carrying more customers than ever before as London’s economy and population continue to grow. This is why we are continuing to invest all of our income to modernise the service, improving reliability, train capacity and frequency and upgrading major stations to reduce congestion.”

Mick Cash, the general secretary of the Rail, Maritime and Transport Union (RMT) said: “The increasing demand is putting the network under massive pressure day in and day out and it needs more staff and more investment to run safely and efficiently, not less.

“The case against ticket office closures, staff cuts and any further assault on budgets by the government is reinforced by today’s news on passenger numbers.”
