Last Friday was the busiest day in history for London Underground, which smashed through a record it had set just three weeks earlier.
The tube network carried 4.725m passengers on Friday the 28 November, according to figures released by Transport for London (TfL).
It beat the last record, set on 14 November, where 4.576m journeys were made on a single day.
That figure was four per cent higher than at the same time last year, which suggests Londoners are really embracing the festive season.
Phil Hufton, London Underground's chief operating officer said:
The fact that we have broken the record for passenger numbers on the Tube twice in three weeks clearly shows that there is an increasing demand to travel on London Underground.
This is why we need to continue to invest in the modernisation and improvement of the Tube network and make sure that we provide an enhanced experience for customers.
The network is carrying out a series of modernisations to its services as it caters for London's growing population.
This includes the upgrade of the Northern line, which is nearly complete, and improvements on the Circle, District & City and Metropolitan lines.
A number of stations - including Victoria, Tottenham Court Road and Bond Street - are also being redeveloped.
