The number of UK train tickets sold last year rose 3.8%, according to the Rail Delivery Group.
The body that represents train operators and Network Rail said there were 1.7 billion journeys made in the UK between January 4, 2015 and January 9, 2016.
That represented 62 million more than in the previous 12 months. Sales in cash terms rose by 6% to £9.4 billion.
Cheaper tickets sold in advance and off-peak tickets had grown particularly strongly.
Sales of super off-peak tickets and anytime fares were both up 10%, while off-peak and advance tickets rose by 5%.
The biggest growth in sales came in London and the southeast, where 4.3% more tickets were sold, while there was a 3.6% rise for seats on long-distance routes.
No figures were available for which ticket types suffered a slide in sales, the BBC reported.
