Losing mobile signal when passing through train tunnels is set to become an annoyance of times gone by, under new Government plans.

The Department for Digital, Culture, Media and Sport, has today launched a call for evidence on how it can "dramatically" improve internet and phone connectivity on Britain's train network by 2025.

At present millions of commuters face the daily frustration of poor signal, preventing them from working and talking to friends and family while travelling.

Under the plans masts will be placed along railways and inside tunnels, meaning each train could get uninterrupted internet speeds of around 1 Gigabit Per Second.

The Government claims this would "future proof the connectivity" and in practice could allow several hundred passengers to stream uninterrupted video content at the same time.

A trial will first take place on the Trans-Pennine route which will initially focus on wi-fi but may also look at mobile coverage, a spokesman said.
