Almost 11,000 horse racing fans are expected to have travelled through Birmingham New Street to the Cheltenham Festival.
Train operator CrossCountry confirmed that they had laid on extra services to cope with demand, revealing that more than 8,000 people had already made the trip since Tuesday.
The number was expected to reach 11,000 by the end of the event.
A spokesperson for CrossCountry said: “We have additional trains running northbound and southbound, and have strengthened with longer trains where possible.”
Meanwhile, Birmingham New Street had introduced crowd management for the duration of the four-day festival.
A queuing system, including a ‘paddock’ for all passengers travelling to and from Cheltenham has been managed by station staff.
