We design and build electrical networks that power railway, tram, and trolleybus systems — ensuring reliability, efficiency, and compliance with the highest industry standards.

Elnos Group is a long-standing partner in the design, construction, and rehabilitation of overhead contact line (OCL/OLE) systems across the region.

Our solutions enable secure and efficient transmission of electrical energy, contributing to the safety, stability, and modernisation of public transport. We operate in accordance with the highest technical and safety standards, while adapting to complex urban and infrastructure environments.

From dismantling existing systems to implementing new ones, our teams execute complete electrical works – including integration and remote-control systems – within strictly controlled timelines, ensuring minimal disruption to ongoing traffic and maximum operational performance.
