More people are travelling the capital by Tube than at any time during the past 152 years.
Statistics released by Transport for London revealed the network’s busiest ever day was October 9, 2015.
A total of 4.735 million customer journeys were made that Friday while 28.614 million occurred in the last week of October, surpassing all previous seven-day records.
Overall, the number of customer journeys on the London Underground has increased by a third since 2001, with the rate of growth increasing in the last five years.
The Tube’s managing director Nick Brown, said: “The network 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.”

"The increasing demand is putting the network under massive pressure day in and day out"
RMT General Secretary Mick Cash said: "The record numbers of tube users shows just what a success the service is and that is down to the hard work of the staff who make it tick.
"The fact that the news comes just as the Government are lining up annual additional cuts at TFL of £700 million a year is deeply worrying to both staff and passengers alike.
"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."
