The government is spending £90 million on improving Wi-Fi speeds on trains throughout the UK.
The improvements will be made first on some of the UK’s busiest lines, including London, Manchester, Brighton, Portsmouth, Bedford and Leeds.
Within three to four years Wi-Fi on trains is expected to be ten times faster than what is currently on offer.
"We all know how frustrating it can be to have our phone calls and internet use constantly disrupted by poor signal while travelling on trains. At the moment it happens too often," said transport secretary Patrick McLoughlin.
Once installed, commuters will get better signal through equipment positioned alongside the track, rather than the current system of having to find a satellite signal as they travel along the line.
A proportion of the £90 million will be funded by the record-breaking fine being handed to Network Rail.
The firm is being punished by the Office of Rail Regulation for missing key punctuality targets on its long-distance services over five years.
