Karlsruhe, Helsinki – 29 January 2026
The Helsinki Regional Transport Authority (HSL) has commissioned INIT to deliver a state-of-the-art on-board system for its entire vehicle fleet. The project includes container-based software, vehicle hardware, and services and will be rolled out across approximately 1,700 buses, trams, metro cars, trains, and ferries. The new system will create a uniform, future-proof platform for vehicle operations across all modes of transport.
At the heart of the solution is the COPILOTcontainer, a Docker-based on-board software platform that delivers all operational, driver, and communication functions of the on-board computer. By consistently leveraging container technology, INIT is advancing the technological evolution of modular open technology platforms while enabling flexible, scalable, and long-term maintainable vehicle IT.
Seamless integration into HSL’s existing ecosystem
A central element of the project is the comprehensive integration of the new on-board system into HSL’s existing IT and system environment. To achieve this, INIT is developing a wide range of interfaces, including connections to passenger information displays, traffic signal priority modems, ticket validators, passenger counting sensors, and existing on-board computer control panels used in trains and metro vehicles.
“We chose a container-based solution because we want a unified, flexible, and future-proof platform for our entire fleet across different modes of transport. Container technology allows us to update and expand functionalities quickly without disrupting services for our passengers. INIT stood out by offering a technically advanced, standards-based, and seamlessly integrated solution that supports both our current operational needs and our long-term development vision”.
Tuomas Savikangas, Director HSL Technology
In addition, INIT is providing vehicle data middleware as a central integration layer between vehicles and backend systems. This middleware initially supports real-time communication based on the Nordic NOPTIS standard and may transition to SIRI in a later phase if opted.
