How Hitachi Rail Is Transforming Urban Transit with Smart, Sustainable Rail Technology

In the heart of Singapore’s urban rail network, a quiet revolution is taking place. Not in the form of sleek new trains or modern stations, but in the invisible intelligence that holds the network together.

At the center of this transformation is Hitachi Rail, partnering with SMRT and Land Transport Authority (LTA) to keep people moving more efficiently and sustainably.

Using Rail Technology to Solve Urban Challenges: Capacity, Reliability, and Sustainability

For decades, rail systems operated on rigid timetables. That worked in the past, but in today’s modern cities, where millions rely on public transit, the margin for inefficiency is much tighter.

It has become vital to upgrade the signaling system on the North-South and East-West Lines (NSEWL), two of the oldest yet most critical lines in the country. Since 2012, an upgrade to the signaling system, known as the SelTrac™ Communication-Based Train Control (CBTC), led to a greater optimization of the network capacity and improved train operations.

Through working closely with key counterparts from SMRT and LTA, the project was a success and has brought about the following achievements:

●    An increase in capacity by 20%: With the SelTrac™ CBTC’s precise control, trains can safely run closer together, reducing wait times and overcrowding, making commutes less stressful, especially during peak hours.

●    An improvement in reliability: Since 2015, delays on the NSEWL have been reduced from one every 150,000 kilometers to less than one every 1,000,000 kilometers, a six-fold leap in reliability over the past decade.

●    An increase in energy savings: By optimizing speed ramp-ups and minimizing hard braking, the system ensures a steady, energy-efficient ride, much like how driving at a consistent pace saves gas.

Hitachi Rail’s work in Singapore is a perfect example of how technology can serve society to deliver genuine, everyday impact.

Higher Sustainability Potential for Hitachi Rail’s New CBTC System with Greater Energy Savings

With a forward-looking approach, Hitachi Rail introduced the Green CBTC Next Gen, a groundbreaking feature of the CBTC system, through a flagship collaboration project with SMRT Trains. At its core, Green CBTC Next Gen uses advanced analytics, machine learning, and energy optimisation algorithms to control how trains move. The system doesn’t just tell trains when to stop or go; it intelligently guides them by predicting and adapting in real time for maximum efficiency.

The results? A remarkable 8% reduction in energy consumption—equivalent to powering over 3,000 homes annually. And this is just the beginning. Future phases aim to raise that number to 15% or more, all without altering the track, stations, or vehicles. The infrastructure remains the same—what changes is the intelligence behind it.

These achievements point to a hopeful truth: solving large societal issues, like climate change and urban congestion, do not always require massive infrastructure solutions. Sometimes, it simply means working smarter with what we already have.

Smart Rail Systems and Predictive Maintenance: Building Resilient Transit Infrastructure with Hitachi Rail

Hitachi Rail’s vision goes beyond efficiency. It is about building resistant, future-proof mobility systems to meet the challenges ahead.

Hitachi Rail has constructed a CBTC Simulation Facility, a digital twin that serves as a virtual replica of the NSEWL network. The digital twin allows engineers to test new strategies, simulate scenarios, and train staff without ever disrupting real operations.

With the future integration of condition-based maintenance, the same sensors and data streams used to optimize train movement can also detect wear, stress, or anomalies in equipment before breakdowns happen. This will prevent costly delays, extend the life of assets, and ensure passenger safety.

Every technological progress matters, be it a line of code, a data point, or a predictive algorithm. It is about making life better for the people who ride the trains on a daily basis, as well as keeping a city sustainable for future generations.

Scaling Innovation for a Smarter Tomorrow

As the success of the CBTC technology unfolds in Singapore, Hitachi Rail is turning its focus beyond the island. The next frontier lies in scaling this intelligence across rail networks worldwide and adapting it to the unique needs of every city.

Hitachi Rail has a strong presence in rail infrastructure in other countries like Hong Kong, South Korea and Malaysia. CBTC technology is powering three key signaling projects across the Kelana Jaya Line, the Ampang Line and the KL Monorail in Kuala Lumpur. More recently, we have been awarded a contract to provide CBTC technology for light rail projects in Taipei.

More than just saving energy or adding capacity, the next part is to create mobility ecosystems that are adaptive, intuitive, and inclusive, where trains run on time and operate in harmony with the needs of both people and the planet.

Looking forward, Hitachi Rail is leveraging data-driven systems, predictive maintenance, and integrated digital platforms to transform every rail line into a smart, sustainable backbone for tomorrow's cities. This momentum is shaping what’s next for smarter, more sustainable urban mobility.
