Swiss operator BLT Baselland Transport AG has contracted Stadler to equip its main network in the Basel metropolitan area with the NOVA Pro communications-based train control system. The project marks a new phase in the automation and digitalisation of the tram and regional train operations managed by BLT.
The NOVA Pro solution has already been tested on the Waldenburg line, where operations are conducted in GoA2 mode, i.e., semi-automated operation. After departure is approved by the onboard crew, the train runs automatically, with the system controlling speed, level crossings, and precise stopping at stations. Stadler and BLT say this line has achieved a punctuality rate of over 99%, making it one of the most reliable in Switzerland.
Gradual implementation starting this year
According to the announcement, starting this year, 38 Tango trams and 25 TINA trams will be gradually equipped with NOVA Pro. The first tests on Line 11 are scheduled for 2027, after which the system will be introduced in phases across the entire BLT main network in the Basel region.
Communication between onboard and ground-based equipment will be carried out via the public mobile network, using 4G/5G technology. Stadler states that the migration to NOVA Pro will take place within the existing infrastructure and technical architecture at BLT.
Expanded Partnership Between Stadler and BLT
Through this project, the two companies are strengthening their long-standing collaboration. Stadler states that interest in the NOVA Pro system remains high, and the Waldenburg line is already being visited by delegations from transport operators in Switzerland and other countries interested in semi-automated operation under real-world conditions.
Silvio Gemperli, head of Stadler’s signaling division for Switzerland, stated that the project represents “a new milestone” in the partnership between the two parties and said that the success on the Waldenburg line demonstrates the potential of the NOVA Pro system.
For his part, Reto Rotzler, BLT’s infrastructure director, stated that expanding the solution to the main network is “the next logical step” following the results achieved on the Waldenburg line.
What Does GoA2 Mean
Automation levels are explained by the GoA – Grades of Automation system, ranging from GoA0, fully manual operation, to GoA4, fully automated operation with no crew on board. In the case of the BLT network, the system operates in GoA2 mode, which means that starting is authorized by on-board personnel, but acceleration and braking are performed automatically by the system.
Levels of automation in railway operations
GoA0 – fully manual operation
GoA1 – manual driving assisted by safety systems
GoA2 – semi-automated operation; the system drives and brakes, but personnel remain on board
GoA3 – automated operation without a driver in the cab, but with personnel on board
GoA4 – fully automated operation, without personnel on board
