Trainline has launched the UK’s first ever train ticket price predictor.

Available in the Trainline app from today, Price Prediction allows train travellers to look into the future and see when advance ticket prices are set to increase over time.

Trainline customers currently save an average of 44 per cent on advance fares, however billions of price prediction data points show that if customers bought their ticket on the day they first searched for their journey, they would save an average of 49 per cent.

Trainline argues they could save more by booking even earlier.

Price Prediction uses billions of data points to predict when advance train tickets are set to increase in price over time, helping travellers to budget for their next trip more effectively.

The new tool gives customers an at-a-glance snapshot of all the opportunities to save money when buying advance tickets in the months and days leading up to travel.

Advance rail ticket pricing is complex, and customers can often miss opportunities to save.

Most train companies release advance tickets around 12 weeks before the day of travel, and once available to buy, they almost always increase in price as the day of travel approaches, so delaying purchase can be costly.

Price Prediction gives complete transparency on the price of advance tickets, helping customers choose the best price for their journey.

Jon Moore, chief product officer at Trainline, said: “Our data scientists have used historical pricing trends from billions of customer journey searches to predict when the price of an advance ticket will expire.

“We now share this information in our app to allow our customers to get the best price possible for their journey.

“We’re introducing more advanced machine learning every day so naturally our predictions will get increasingly accurate.

“Our mission is to make train travel as simple as possible and price prediction is the first in a long line of predictive features we have planned to help customers save time and money.”

The new tool is the latest in a series of smart features for travellers in the Trainline App and follows the launch of BusyBot which uses crowdsourced data to identify the quietest parts of the train and help customers find a seat.

Mobile tickets help customers save time queuing to collect at the station and real-time travel information including platform numbers and journey/delay information allows travellers to be in complete control of their journey, on-the go.
