A number of train operators are selling cheaper advanced tickets, which are quota controlled and can quickly sell out.
Europe's leading independent train ticket retailer, Trainline, revealed that its customers saved £21.8 million last year by purchasing advance return tickets for travel between December 16-31 rather than buying tickets on the day of travel, excluding booking fees.
A survey of 2,000 British adults commissioned by the company found that expense is a source of frustration over the festive period for 39% of people, followed by family arguments (22%) and traffic jams (21%).
More than half (53%) of people prefer to travel by train over Christmas as they find it relaxing, while 40% want to avoid congestion on the roads.
Almost one in four (24%) enjoy the option of catching up on sleep during the journey home, while 19% want the option of checking social media.
