Transit projects worldwide struggle with costly, repetitive system integration. DAINSY solves this by providing a ready-made, real-time integration platform that connects legacy and modern systems reliably, reducing delays and preparing networks for AI-driven operations.
Why building everything from scratch is no longer sustainable for the rail industry
Globally, new rail and metro projects are being launched at an unprecedented pace. From urban light rail to national high-speed corridors, governments and operators are investing heavily in the future of mobility. Across North America, Europe, the Middle East, and Asia, one issue consistently slows projects down, increases costs, and frustrates engineers, and that is system integration.
Every new project faces the same dilemma; SCADA systems, signalling, energy management, sensors, IoT devices and cybersecurity layers all need to work together. However, these systems are rarely designed to communicate across vendors, legacy infrastructure, or modern cloud environments.
What happens next is predictable, as every time, integration teams end up custom-coding each connection. Valuable engineering hours are spent reinventing the same basic tools, workarounds, and connectors — only for these efforts to be abandoned at the end of each project. The process begins again on the next line, the next project.
It is not sustainable. Not for budgets. Not for delivery schedules and certainly not for the engineers and operators who need reliable, repeatable solutions.
Resologi created DAINSY as a real-time data integration platform that acts as a toolbox for system integrators.
Instead of starting from scratch on every project, DAINSY provides a library of proven tools, connectors, and frameworks that can be adapted to each unique environment. It was designed with integrators and engineering firms in mind, but benefits the entire ecosystem: operators, authorities, and ultimately the passengers who depend on efficient, resilient transport.
From the earliest specification, DAINSY was designed for uninterrupted 24/7 operation. Its architecture ensures maximum compatibility between software and hardware components, enabling continuous operation in mission-critical environments.
One Platform, Many Roles
DAINSY (short for Data Integration System) functions as a modular operating system for infrastructure. It is capable of bridging legacy and modern systems in real time, securely and at scale.
Key capabilities include:
- Edge computing for low-latency control and resilience at the device level
- Vendor-agnostic interoperability, supporting protocols such as Modbus, OPC-UA, MQTT, BACnet, SNMP, and more
- Digital twin simulation, allowing testing and optimisation before going live
- Historisation and diagnostics, enabling deeper operational insight and performance benchmarking
- Cybersecure architecture, aligned with global standards such as ISO/IEC 27001:2022
Its high-availability design ensures continuous service delivery and seamless failover, even in complex multi-vendor environments.
Whether deployed as a local SCADA replacement or integrated into a regional “super SCADA,” DAINSY adapts to the role required.
Built for Integrators. Trusted by Operators.
Unlike closed OEM platforms, DAINSY was conceived in the field by engineers who had experienced the headache of integration.
“DAINSY was never about replacing every system,” explains Julien Ciesla, founder and technical lead at Resologi. “It was about giving integrators a sustainable toolbox — one that makes projects more efficient, more secure, and more repeatable.”
Above all, DAINSY was engineered from day one to operate reliably 24/7. Its architecture ensures robust coordination between software and hardware layers, guaranteeing continuous uptime in critical operational environments.
- For integrators, DAINSY shortens time-to-commissioning with pre-configured connectors, real-time testing environments, and open APIs for custom extensions.
- For engineering firms, it simplifies design, especially when incorporating technologies from international suppliers that may lack common standards.
- For operators and authorities, it delivers real-time visibility, supports predictive and preventive maintenance, and reduces dependence on single vendors.
Proven Across Continents
DAINSY is already proven in some of the world’s most demanding transit environments:
- Paris Metro (RATP Dev) – Energy management modernisation
- Montreal REM (Light Rail) – Real-time OT/IT integration
- STM (Montreal Metro) – Legacy SCADA harmonisation
- Cairo Metro – Infrastructure diagnostics and control integration
- Alstom projects worldwide – Bridging OEM systems with operator requirements
Together, these projects demonstrate that the challenges of integration are universal — and that DAINSY’s approach works across Europe, North America, and the Middle East.
Looking Ahead: AI-Ready Integration
The future of mobility is data-driven. Predictive analytics, AI-assisted control, and advanced simulation will become central to how transit systems are operated and maintained.
DAINSY is built with this future in mind. The platform is AI-ready, supporting predictive and preventive control, digital twin workflows along with advanced historisation. This enables teams to model changes before they are deployed, saving time and reducing operational risk. Its architecture, designed for continuous 24/7 environments, provides a stable, high-availability foundation for future AI modules and predictive engines.
Resologi is planning the rollout of an Affiliate Partner Program in early 2026, enabling certified integrators worldwide to deploy, configure, and support DAINSY locally. This model will expand our reach while preserving the flexibility and openness that define the platform.
Canadian Innovation, Global Reach
Resologi was founded in Montreal, Canada, by engineers with decades of experience in infrastructure operations and industrial cybersecurity. Our mission is clear: make system integration faster, safer, and more sustainable — without forcing costly system overhauls.
Today, the company is expanding rapidly across North America, Europe, Southeast Asia, and the Middle East, partnering with engineering firms and system integrators who share the same vision, that integration should not be an obstacle, but an enabler of modern mobility.
