FIRST Hull Trains has launched what it says is the world's first free 4G wi-fi service for passengers.
It will improve the speed of onboard internet and means users can watch catch-up TV and shop online as they travel, the company said.
The service allows browsers to sign up once and automatically reconnect every time they use the railways. It is aimed at businesspeople on services to and from London.
Managing director Will Dunnett said: "First Hull Trains is already one of only a handful of train operating companies offering free wi-fi.
"Now, we are taking our commitment to innovation and market leadership a step further by trialling the very first 4G-enabled wi-fi single sign-up solution to all passengers.
"The service is faster, more reliable and will give an improved experience for our passengers and that's why we've made this investment ahead of every other public transport company in the UK."
Other operators have also been looking into the service.
Virgin Trains announced in June it would introduce the next-generation technology on the West Coast Main Line.
The company said it would fit 76 Pendolino and Super Voyager trains with upgraded wi-fi.
For Mr Dunnett, it is a natural progression as smartphones and tablets become more commonplace.
He said: "People have wanted to be able to get online when they travel for several years, which is why we've always given all passengers free access to our onboard wi-fi.
"But with the demand and necessity growing, our passenger feedback demonstrates they require a better service, so we are proud to be the first to provide 4G."
In addition to wi-fi as they travel, the service will also give passengers free access to more than 22,000 nationwide hotspots run by internet firm The Cloud, including Hull's Paragon Interchange.
The upgrade is being provided by mobile connectivity company Icomera, which supplied the travel company with its original onboard internet in 2010.
First Hull Trains has also signed an exclusive deal with ITV so passengers with smartphones can access its programmes after they have aired without delays or freezing.
The channel's business development manager Ben Halabi said: "A key part of our strategy is to make our content available to viewers wherever and whenever they want it.
"We are delighted to be partnering with First Hull Trains to offer their customers access to a selection of ITV programmes at a steady and consistent speed, throughout their journey."
First Hull Trains internet has been free for users since its launch.
Many other operators charge for access to their networks.
Mr Dunnett said: "This industry-first initiative will provide all our passengers with access to a high-quality viewing experience through their smart devices.
"Many of our travellers are on board with us for up to two and a half hours and this new service means they can still access and enjoy selected episodes of popular soaps, dramas and programmes while they travel. And it's free."
