Trade bookings currently account for more than 85% of the operator’s total rail business.
Simon Chambers, general manager of Fred Holidays, said: "It is clear how important our trade partners are and that we value them highly.
"Growth plans in 2023 continue to accelerate for our rail journeys programme with the clear desire of British holidaymakers to opt for this mode of transport – whether that is to avoid airports or from a more sustainable point of view."
In 2022, the operator saw turnover growth of its rail product exceed 300% compared to 2021.
