Nestled along the Danube, Bratislava, Slovakia’s capital and a key transport hub in Central Europe, is home to a railway network where historic heritage meets the needs of modern mobility.
A symbol of this continuity is the twin tunnels of Lamač. Built in 1848 and 1902 along the route to Prague, they are a remarkable example of infrastructure with great historical significance, while also offering a fascinating comparison of construction techniques from different eras. The first tunnel, approximately 700 metres long, was excavated entirely by hand using pickaxes, shovels and explosives, in successive sections from the bottom upwards, following the Austrian method. Today, it holds the distinction of being Slovakia’s first railway tunnel and is recognised as a National Cultural and Technical Monument. Fifty years later, in 1902, a second tunnel, approximately 595 metres long, was built alongside it to double the track towards Prague and Vienna without interrupting international traffic. This second tunnel was constructed in a single section from the bottom upwards using the English method, taking advantage of a better understanding of the type rock involved, thus speeding up the work. Still fully operational and electrified today, the two tunnels are a masterpiece of civil engineering and remain essential to rail traffic.
Furthermore, as part of the Trans-European Transport Network (TEN-T), Bratislava is now at the centre of major infrastructure development projects. Among these, the extension of the railway line between the Central Station and Lamač stands out. This project involves the construction of a new tunnel and the widening of the tracks to four lanes to improve the flow of both metropolitan and international traffic. In addition to these works, investments are being made in major national routes, such as the modern Turecký vrch tunnel along the Bratislava–Žilina route, representing a network that is constantly evolving towards higher standards of speed and capacity.
In projects of this scale, ensuring the highest possible levels of safety and visibility inside the tunnels is a fundamental requirement. To meet these needs, the lighting design for several tunnels was carried out by Disano, a global leader in the infrastructure lighting sector. The solution involved the use of Rodio lighting fixtures, specifically developed to deliver the highest levels of efficiency, robustness and reliability in complex structural environments, such as railway tunnels.
These luminaires create uniform, stable (low-flicker) and glare-free lighting, helping to improve visibility and enhance the overall safety of the environment inside the tunnels. Furthermore, the polyester powder coating provides high resistance to corrosion and weathering, ensuring maximum durability throughout the luminaire’s entire service life.
At the same time, the high performance of Disano’s LED light sources enables a significant reduction in energy consumption and operating costs, supporting efficient and sustainable management over the long term.
These operational advantages are complemented by an extremely refined design: Rodio’s sleek, discreet lines facilitate harmonious integration into the infrastructure, combining functionality and elegance in a single solution.
Thanks to Disano’s spotlights, Slovakian railway tunnels now benefit from safe and efficient lighting, achieving excellent visibility, high visual comfort, outstanding energy efficiency and cost-effectiveness.
