Switzerland has reached a new milestone in digital railway operations, with BLT Baselland Transport AG becoming the first operator in the country to deploy semi‑automated GoA2 services on the Waldenburg Railway. The approval, granted by the Swiss Federal Office of Transport (BAV), marks the debut of this operating mode on the Liestal–Waldenburg line and positions BLT at the forefront of modern, technology‑driven rail innovation.
A Landmark Introduction for Swiss Rail
The transition to semi‑automated operation is powered by Stadler’s newly developed signalling technology. At the core is the NOVA Pro train protection system—an entirely new communications‑based train control (CBTC) solution created at Stadler’s Wallisellen site. The system facilitates direct communication between trains and wayside equipment, enabling a fully digital approach to managing train movements.
A Modernisation Programme with a Clear Vision
The Waldenburg Railway has undergone extensive renewal in recent years, and the introduction of GoA2 is the latest step in a long-term digitalisation strategy. Since late 2022, the line has benefited from ten new Stadler trainsets built in Valencia. Alongside this, BLT has completely upgraded the 13‑kilometre route, investing in new track, modernised stops and an advanced generation of control and signalling systems.
A pivotal development is the move away from conventional lineside signalling. Under the new GoA2 regime, the CBTC system manages the full driving task once the driver closes the doors and authorises departure. Speed regulation, adherence to maximum permitted speeds, level crossing sequencing and precise stopping at stations are all handled automatically. This reduces routine workload for drivers, supports consistent performance and enhances punctuality. The driver’s role shifts to supervising the journey and intervening only when required.
Building Towards Full Automation
BLT’s automation roadmap extends beyond the mainline. By the end of 2026, the operator plans to introduce fully unattended depot movements at its newly constructed Waldenburg facility, achieving GoA4 automation within depot limits. This would represent the next major step in transitioning the railway towards increasingly automated and efficient operations.
Industry Leaders Highlight the Benefits
“GoA2 represents a major step forward in automated rail operations. Train services will become more uniform, resource-efficient and energy-efficient. The Waldenburg Railway will operate with even greater punctuality. GoA2 helps reduce delays and prevent early departures from stations. This is a significant added value for our passengers,” says Philipp Glogg, Chief Technical Officer of BLT.
Marc Trippel, Executive Vice President Division Stadler Signalling, adds: “We are very proud to be implementing this forward-looking project together with the Waldenburg Railway. For Stadler Signalling, it represents an important milestone in the further development of modern, digital train control systems – and at the same time a significant step for automated rail transport in Switzerland.”
