Such was the novelty of that first underground journey that thousands of people queued for hours to take a ride and, as far as we know, all arrived on time. The line, which connected mainline stations at Paddington, King's Cross and Euston with the city, was a great success and soon 26,000 people a day were travelling on it.
One hundred and fifty years on and the Tube has passed its biggest test - the Olympics - with flying colours, is on track for another round of extensions and still manages 3.5 million journeys every day.
London Underground and the London Transport Museum have orchestrated a season of events to mark the anniversary: the most exciting of which is the return of steam to the Tube. Metropolitan Locomotive No1 - a distinguished old engine built in 1898 - will be pulling carriages on ceremonial journeys along the line at selected times throughout the year.
An exhibition at the London Transport Museum will display the poster art that has adorned the walls of the Underground for more than a century.
