Challenges Facing the Overhead Contact Line Industry

The construction and maintenance of railway systems are facing increasing technical, financial and organisational challenges. Long planning, approval and construction processes, rising certification requirements, and extensive documentation and administrative obligations are leading to higher costs and longer project timelines. At the same time, the requirements relating to the landscape and structural integration of new installations are increasing.

Planning reliability and resources

The planning, construction and maintenance of overhead contact line systems are becoming increasingly complex. Operators maintain numerous framework agreements with industrial companies, which in some cases means that individual suppliers lack the critical scale and utilisation required. At the same time, the shortage of skilled workers is becoming more acute, particularly among site managers and mechanics responsible for maintaining specialised machinery.

Improved long-term planning of projects, personnel and machinery is therefore essential. Investments in specialised machinery – increasingly also battery-powered – must be taken into account through appropriate tendering processes and sufficient utilisation. The question of “Make or Buy?” in maintenance should also be discussed further. The industry is convinced that shifting a greater share of the value chain towards industrial partners can help reduce overall costs.

Digitalisation and BIM

Digitalisation and BIM offer significant potential for greater efficiency and cost reduction. In practice, however, additional effort is sometimes created by parallel 2D and 3D processing, missing baseline data and unclear interfaces.

A faster transition to direct 3D planning is therefore needed, together with improved data quality and clearly defined responsibilities – particularly at the interfaces between the track infrastructure and overhead contact line systems. Proprietary planning tools developed by individual operators should be critically reviewed. Scalable solutions that can be used across the industry are more efficient and foster innovation.

Standardisation and international scaling

Overhead contact line systems and their construction methods are only standardised to a limited extent internationally. This makes it more difficult to scale Swiss solutions abroad. Given the limited market potential in Switzerland, however, exports are essential.

Swiss suppliers have a high level of technical expertise and are able to respond quickly and flexibly. At the same time, their costs are sometimes higher. A balance is therefore needed between quality, innovation, speed and cost, along with further progress towards international standardisation.

Innovative solutions such as overhead conductor rail systems demonstrate the industry’s strong export potential: they are space-saving, robust and comparatively easy to install. Nevertheless, significant barriers to the introduction of new technologies remain in various countries.

Innovation and collaboration

Innovation should be developed at an early stage and jointly by operators, industry, planners and authorities. Tenders must be technology-neutral and designed in a meaningful way. Risks should be identified early and discussed transparently – with the objective of finding solutions rather than assigning blame.

The Hagenbach test tunnel provides an excellent platform for testing new technologies under real-world conditions and for further developing them for both the Swiss and international markets.

Conclusion

The industry needs greater planning reliability, standardisation, digitalisation and capacity for innovation. At the same time, administrative, certification and contractual burdens must be reduced.

The overhead contact line industry should not be regarded merely as a supplier, but as a strategic technology and innovation partner for operators. Only through early and collaborative cooperation can costs be reduced, expertise secured, and innovative Swiss solutions successfully scaled internationally.
