Summary
The electric bus fleet of Bern Transport Authority Bernmobil is struggling with recurring charging system failures. On Saturday, February 1, 2026, an electric bus on line 21 could not recharge at the Bremgarten terminus and caused a service cancellation. While Bernmobil reports technical improvements, reliability remains below expectations. In parallel, the BLS Foundation is creating a railway experience world in Burgdorf and wants to revitalize the historic locomotive depot with cultural events and a bistro.

Clarus Lead
The electrification of bus transport in the city of Bern reveals a central weakness: charging systems are not yet reliable enough. A concrete failure on line 21 shows that despite six years of experience with electric buses, technical problems arise at the interface between vehicle and charging station. Bernmobil plans complete conversion by 2035, but cannot predict when trouble-free operation will be achieved. In parallel, the BLS Foundation is investing in Burgdorf in a future model: historic trains are to become an attraction of an experience world.
Clarus Original Research
Clarus Research: The error did not affect the vehicle itself, but the interface between bus and charging station – a system level often overlooked. Bernmobil confirms: suppliers and operators are working on error analysis, but report "fewer and fewer" problems, without providing specific numbers.
Classification: The reliability crisis is not a vehicle-specific problem, but a technology maturation problem. Other transport operators struggle with the same charging system failures. This points to lack of standardization or insufficiently tested interface architecture.
Consequence: Passengers must continue to expect service cancellations. The planned conversion by 2035 is announced without reliability guarantees. Decision-makers should prioritize investments in redundancy systems and test sites before the fleet grows further.
Detailed Summary
Electric Bus Failures in Bern
On Saturday, February 1, 2026, between 7 and 8 p.m., line 21 from Bremgarten to Bern station failed. The bus could not recharge its batteries at the terminus – the charging station was blocked. Rolf Meier, communications director of Bernmobil, confirms: the cause could lie in the charging system, the bus itself, or the technical interface. An exact diagnosis is pending.
Electric buses have been running in Bern since 2019, so for over six years. Line 21, which was affected, was converted to battery operation more than two years ago. Nevertheless, charging system problems occur regularly – trend declining, but not eliminated. Bernmobil justifies the problems with still "relatively new technology" and points out that other transport operators must also address similar challenges.
By approximately 2035, all buses at Bernmobil are to be converted to electric. There is no concrete forecast for when reliability is guaranteed.
BLS Foundation: Railway Experience World in Burgdorf
The historic locomotive depot in Burgdorf, operated by the BLS Foundation for almost 15 years, is to be redesigned into a cultural attraction. Instead of an isolated location between construction sites and rail traffic, the foundation plans more events, a bistro, and regular guided tours.
Hans-Peter Ernst, former regional managing director of the BLS Foundation, emphasizes the potential: interest in historic trains and railway history is high. Guided tours, locomotive simulators, and special trips show strong visitor numbers. The experience world is to revitalize the neighborhood and in the future also be mixed with residential and working spaces.
Key Messages
- Electric buses in Bern have systematic charging system problems, despite six years of experience.
- Error causes often lie at the interface between vehicle and infrastructure, not in the bus itself.
- Bernmobil plans complete electrification by 2035, without reliability guarantees.
- The BLS Foundation is creating a model in Burgdorf for cultural reuse of railway heritage.
- Passengers must continue to expect service cancellations.
Stakeholders & Affected Parties
| Stakeholder | Role | Status |
|---|---|---|
| Passengers | Directly affected by failures | Challenged |
| Bernmobil | Operator, bears financial burden | Under Pressure |
| Charging Station Suppliers | Technical responsibility | Challenged |
| BLS Foundation | Culture and heritage | Benefiting |
| City of Bern / Burgdorf | Political and spatial responsibility | Investing |
Opportunities & Risks
| Opportunities | Risks |
|---|---|
| Learning Curve: Error analysis leads to system improvements | Reputation: Repeated failures undermine confidence in e-mobility |
| Redundancy Potential: Multiple charging systems per station reduce failure risk | Delay: Without clear reliability targets, transition remains uncertain |
| Experience World Burgdorf: Historic trains become location advantage and tourist asset | Mixed Use: Residential + Working + Transport can create new conflicts |
Action Relevance
For Decision-Makers at Bernmobil:
- Prioritize redundancy audits for each terminus.
- Define concrete reliability targets (e.g., 99% availability) and deadlines.
- Establish real-time error tracking and public transparency updates.
For Passengers:
- Plan buffer time when using line 21 until mid-2026.
- Use Bernmobil's feedback channels to document failure patterns.
Observation Indicators:
- Number of monthly charging system failures (should decline).
- Time to error analysis and resolution.
- Expansion of redundant charging stations at termini.
