The future (of Services) is digital: HealthHub

Operators can then trigger precise maintenance at the most advantageous time: during off hours, when passengers and timetables won’t be affected.

In a larger sense, HealthHub drives predictive maintenance and data-driven decision-making, reducing downtime, optimising maintenance schedules and ultimately improving service quality.

Beyond availability

HealthHub also drives condition-based maintenance that reduces waste. For example, HVAC filters, once replaced every three months, are now changed every six to seven months thanks to differential-pressure monitoring - halving annual material use while streamlining planning.

Over time, HealthHub has evolved into a strategic solution for our customers. Part of this strategy is a promise to make sure all Alstom trains are CBM (condition-based maintenance) ready when leaving the factory.

In addition, it integrates with other systems such as the Maintenance Management System (MMS), automatically converting alerts into traceable work orders. This scalability and adaptability make it a powerful tool for supporting the digital and services strategy.

Going further, HealthHub isn’t limited to Alstom employees. Our customers can access the platform as part of larger service contracts. “These service offerings create full transparency and more intimate customer relationships,” Nicolas-Kryzhko explains.

In action: the Réseau express métropolitain (Montreal)

On the Réseau express métropolitain (REM) in Montreal - one of Alstom’s largest service contracts - HealthHub ensures reliability on a network that will ultimately stretch 67 km. It’s the most advanced automated rail system currently in commercial service in the world.

“We run about 20 hours a day and have only a three-hour window at night - digital tools are how we make maintenance happen on time,” explains Frédéric Sanchez, Director of REM Special Maintenance Projects.

As part of a €10 million (CAD 16 million) investment, HealthHub brings together data and insights from several complementary modules to make off-hours repairs possible. Onboard measurement systems continuously record track and catenary geometry during passenger service, effectively turning commercial trains into rolling inspection vehicles.

At the depot, TrainScanner™ - think of a giant MRI machine of lasers and cameras - captures high-resolution imagery of each train as it passes through, measuring pantograph carbon and wheel diameters while detecting issues such as missing screws or impacts.

Meanwhile, on an automated line with no driver to sense irregularities, HealthHub monitors the current of door motors at every station stop. “So far, 100% of door alerts we investigated corresponded to a real issue,” notes Sanchez.

Uninterrupted service and greater cost efficiency - HealthHub shows how we can exploit emerging digital technologies to position rail as the logical choice for tomorrow’s mobility.

Technology & Innovation

The future (of rail) is digital
In our past Journeys together, we told you about the boxes rail must tick to become the smart choice for the future of mobility:
- Rail must be tough and reliable. Passengers must think of rail as a secure, resilient, comfortable means of transport that they can rely on.
- Rail must be available and useful for all. The population is growing and aging. People are also using rail for more varied and bespoke purposes.
- Rail must be efficient and cost-effective. Governments and decision-makers must think of rail as a wise long-term economic investment.
- Rail must respect the environment. In a world of diminishing fossil fuels and natural resources, rail must embrace alternative energies and novel materials.
The red (perhaps LED?) thread running through all these topics? State-of-the-art innovation powered by over a century of rail experience.

Norway's train control upgrade: Paving the way for sustainable transportation

Moving people and things around the world creates a lot of pollution. In fact, it's responsible for more than a third of all energy-related carbon dioxide emissions[1]. That's why we need to find better ways to move. Norway, famous for its beautiful fjords and its dedication to protecting the environment, is taking a big step forward. They're upgrading their entire railway network, from the tracks to the trains themselves. This isn't just about making it easier to get from place to place. It's about using trains to cut down on pollution.

Tackling transport emissions requires a multi-faceted approach. The potential of modernised railway networks to move large volumes of people and goods with low environmental impact is immense. Norway’s transformative project includes modernising over 4,200 kilometres of track and equipping more than 400 trains with cutting-edge train control technology. This project success relies on collaboration among various stakeholders, including providers of trackside signalling, train management, and Alstom, playing a key role in integrating the intelligence onboard the trains that weave the rail network together.
