Almost a fifth of passengers say they are happy with the Wi-Fi service on Southeastern trains - despite the fact it doesn't exist yet!

None of the company's trains provide internet, yet 18% of passengers in a national poll said they were satisfied with Wi-Fi on the service.

This comes after passengers were promised by Rail Minister Paul Maynard last year that Southeastern would benefit from an investment of nearly £50m.

“We are investing nearly £50m to roll out free, fast and reliable Wi-Fi on trains and I am delighted that Southeastern passengers are set to be among those to benefit," he said.

"[We] are determined that 90% of all trains will have access to Wi-Fi by the end of 2018.”

Southeastern Managing Director David Statham said: “There is still a big job to do, but we are closer to delivering internet connectivity on all our trains.

But now, Southeastern says Wi-Fi will not be available on any of its trains until the end of winter.

A Southeastern spokesman said: "Southeastern intends to launch a new, free Wi-Fi system for all of our train services in the very near future as part of our £78 million programme of investment to improve the journey experience for our passengers.

"Working together with the Department for Transport and other partners, we hope our passengers will enjoy the benefits that this will bring by giving them easier access to the internet, travel information, emails and social media."

The National Rail Passenger Survey, published yesterday by Transport Focus, consulted more than 50,000 rail passengers on their satisfaction with various aspects of train travel.

In this year's survey, Southeastern trains were ranked joint lowest for internet reliability, along with Great Northern.

With a fleet of more than 350 trains, Southeastern covers around 1,000 miles of track between Kent, London, and parts of Sussex.

Internet services on Heathrow Express trains were ranked highest, with 71% of passengers saying they are satisfied with its reliability.

The overall satisfaction score for Wi-Fi across all operators in Britain was just 30%.
