Starlink put to the high-speed test: here’s how to get 300 internet on Italo trains

Satellite connection trial on the Bologna–Milan route: up to 192 Mbps, video calls and streaming without interruptions. 19 out of 51 trains have already been fitted; the entire fleet will be completed by March 2027

In Bologna, the satellite signal is not detectable. The train is stationary in the underground high-speed station, and the speed test shows 11.2 megabits per second for download, 12.2 for upload and 90 milliseconds of latency. But there are clearly metres of concrete above the train, and Starlink – the satellite network run by Elon Musk’s SpaceX – doesn’t work without a clear view of the sky. Italo has signed an agreement with Starlink to provide connections worthy of the name even whilst travelling.

Ten minutes is all it takes for the picture to change. Once we’ve left Bologna heading towards Milan, the download speed rises to 137 Mbps, the upload speed to 8.7, and the latency drops to 69 milliseconds. Shortly afterwards, the connection reaches 192 Mbps. This is not quite the 400 Mbps-plus achieved by Italo during almost a year of testing on trains travelling at 300 kilometres per hour, but it is enough to show that train Wi-Fi need no longer be the lottery that passengers have become accustomed to.

More than half the fleet covered

The promise from the rail operator, which is part of the MSC Group, is that all of this will become a guaranteed reality for Italo passengers, on any train and anywhere in Italia. “By the end of the year, 45 out of 51 trains will be fitted with the system. By March, we will have completed the work on the entire fleet,” says Gianbattista La Rocca, CEO of Italo, speaking to Il Sole 24 Ore. Currently, 19 trains are equipped with this system; by the end of September, this figure will rise to 27, representing over half the fleet. Then the roll-out will accelerate: 45 by December and all 51 trains currently available by March 2027. The new trains will be fitted with the system as standard, just like the Siemens trains destined for Germany.

Staying connected whilst travelling

At the heart of it all lies an issue that no one can hide: the quality of the connection, which epitomises one of the small yet significant paradoxes of Italian transport: travelling at breakneck speed whilst, at the same time, having an internet connection that does not always (or perhaps it would be better to say ‘rarely’) manage to keep up.

The agreement between Italo and Starlink aims, as mentioned, to make all this a thing of the past. “The technological investment in connectivity cost just over 10 million for the installations on the trains,” explains La Rocca. Added to this is “a few million euros a year” for service and maintenance. The internet connection is free of charge: it serves to improve quality and, above all, to attract business and international tourism.

The race on the Milan–Bologna route

So, the test. The trial on the Bologna–Milan route is, above all, a test of everyday life. A video call remains stable. Eight episodes of a series on Amazon Prime Video are downloaded in just over three minutes. The Juventus v Milan highlights on DAZN stream without any buffering. The most interesting result, however, isn’t the peak speed recorded in the test: it’s that for most of the journey, you forget you’re using the train’s Wi-Fi.

The transition from satellite to 5G

Behind the scenes lies a hybrid architecture. The system developed by Nomad Digital (the infrastructure provider) automatically selects, moment by moment, the best connection between Starlink and the 5G mobile network. Passengers do not need to do anything. How many people will be connected? Luca Chiti, Head of New Projects Operations at Italo, who was travelling with us during the test, reports from the dashboard that monitors the Nomad infrastructure that there are currently 143 people connected. All at the same time.

The issue of the tunnels

The weak point remains underground. Inside the tunnel, the antenna loses contact with low-orbit satellites and Starlink cannot function. This is where the other available networks come into play. Upon exiting the tunnel, however, contact with the satellite is re-established in milliseconds and the disruption is kept to a minimum. This is the physical limitation of satellite technology. Whilst this may not affect films or videos being watched, when using remote systems (such as the editorial system of Sole 24 Ore), it may necessitate closing the programme and then reopening it to continue operations.

Office on the move

The challenge, however, lies precisely there: for those travelling on high-speed trains – particularly for work – to ensure that an hour on the train is no longer time spent idly, but time for meetings, office work, streaming and cloud computing. And at this stage, the quality of the connection could well become almost as much a factor in the competitive landscape between operators as prices and on-board services. Italo has already decided to introduce 5G and Starlink on the 26 Velaro trains ordered from Siemens for deployment in Germany from 2028.

We arrived in Milan without breaking the 400 megabit record, but with a result that is perhaps more useful. The connection coped with videos, downloads and video calls without turning the journey into an unequal battle with the infamous loading wheel. There are still the tunnels: an inevitable dead spot for the satellite signal. But the real news isn’t 192 megabits of internet on a high-speed train. It’s being able to stop thinking about it. At last.
