• High-flex coaxial cables capable of maintaining integrity under continuous train vibration and movement.
• Low-loss RF connectors built for high-speed data integrity in real-time applications like surveillance, control systems, and infotainment.

HUBER+SUHNER’s solution was selected after a competitive technical evaluation process led by Italian-Thai Development, the engineering, procurement, and construction (EPC) contractor. Sources indicate that HUBER+SUHNER's proven reliability in hostile and high-vibration environments played a decisive role.

Elevating Data-Centric Rail Operations

With the increasing digitization of urban transit systems, the ability to transmit data securely, quickly, and without degradation is essential. Bangkok’s MRT Orange Line Phase 3 is integrating a more data-centric approach, where trains not only move people but also stream data in real time.

The onboard-to-platform communications HUBER+SUHNER enables will support vital applications such as:

• Passenger information systems
• Automated train control (ATC)
• Predictive maintenance sensors
• Video surveillance streams
• Emergency alert mechanisms

These require fault-free communication across diverse operating conditions, including fluctuating temperatures, vibration shocks, and electromagnetic interference from nearby systems.

HUBER+SUHNER’s cables are engineered with multilayer shielding and enhanced insulation to maintain signal integrity under such stress. This is vital in a tropical urban rail environment like Bangkok, where humidity and thermal expansion can compromise subpar systems.

A Critical Step for Thailand’s Transport Connectivity Ambitions

Thailand’s government has been actively seeking partnerships that support infrastructure digitalization. With the Eastern Economic Corridor (EEC) megaproject and various smart city programs in motion, high-performance transport data networks are seen as a backbone of national development.

The Orange Line serves as a model for future transit projects in the region, and HUBER+SUHNER’s selection reflects growing confidence in Swiss-built infrastructure solutions.

Dr. Urs Ryffel, CEO of HUBER+SUHNER, noted in a press statement, “We are proud to support Thailand’s transformation into a smart mobility hub. Our role in this project confirms that high-performance connectivity is no longer optional—it is essential for modern transit operations.”

The sentiment is echoed in Bangkok’s urban planning circles, where demand for better data reliability and commuter security is accelerating. By incorporating European standards in cable architecture, the project sets a new bar for Southeast Asian metros.

Italian-Thai Development's Technical Strategy

ITD, Thailand’s leading infrastructure builder, has made notable strides in adopting international best practices. In its tender documents for the Orange Line, ITD emphasized lifecycle performance, maintainability, and modularity.

HUBER+SUHNER’s modular system architecture aligns well with this vision. The cable solutions include smart routing features, allowing for efficient replacements, upgrades, and maintenance—key aspects in a 24/7 rail operation.

The integration process will be overseen by a joint team of Swiss and Thai engineers, with training and handover sessions planned for local operators in late 2025. This technical upskilling is part of the Thai government’s local content and technology transfer policy under its PPP-driven rail infrastructure strategy.

Global Supply Chain Resilience in Action

One reason HUBER+SUHNER was able to secure this contract is its proven supply chain resilience. Amid global component shortages, the company has maintained reliable delivery timelines through vertically integrated production and diversified warehousing across Europe and Asia.

For the Bangkok MRT project, key components will be manufactured in Switzerland and Poland, with final cable assemblies completed in the company’s ASEAN regional hub in Malaysia. This reduces logistics risk and aligns with local just-in-time supply preferences.

Moreover, the Swiss firm is implementing a digital twin-based cable testing and documentation suite, ensuring that every shipment meets operational tolerances. This offers Bangkok MRT stakeholders real-time quality assurance and predictive failure analytics, which were part of ITD’s scoring criteria.

Real-World Impact: What Commuters Will Notice

For Bangkok’s daily commuters, the impact of this upgrade won’t just be technical. The real-world benefits include:

• More reliable train operations: Fewer unexpected halts due to signal loss or control issues.
• Improved safety features: Enhanced response times from surveillance and control systems.
• Better passenger information systems: Real-time updates about train arrival, service interruptions, and safety alerts.
• Faster rollout of onboard Wi-Fi and infotainment: Enabled by high-bandwidth cables with minimal signal degradation.

In essence, commuters can expect smoother, smarter, and more connected travel experiences—critical in a city where average rush-hour commutes often stretch beyond 90 minutes.

Strategic Foothold in Asia-Pacific

This contract further expands HUBER+SUHNER’s footprint in Asia-Pacific’s rail sector. The region is undergoing a metro rail boom, with new lines planned across Indonesia, Vietnam, India, and the Philippines. The Swiss firm has previously supplied systems for Taiwan’s High-Speed Rail, Singapore’s MRT, and Australia’s Sydney Metro.
