Overview: Tech fault triggers M2 outage between Ouchy-Olympique and Bessières
A technical fault forced a pause on Lausanne’s M2 metro on Monday afternoon, interrupting service on the stretch between Ouchy-Olympique and Bessières in the middle of the rush hour. The disruption prompted Transports publics Lausannois (TL) to deploy replacement buses to maintain mobility for passengers who rely on the line every day.
What happened and where
TL reported that the fault affected the section linking the waterfront stop Ouchy-Olympique with Bessières. Trains could not run on that segment, though the remainder of the M2 network remained in operation. Engineers and transport staff were mobilized to diagnose the issue and begin the process of restoring service as quickly and safely as possible. The incident was described as technical in nature, not due to an external event, and an inspection was launched to determine the root cause and appropriate remediation.
Impact on passengers
With the disruption coming during the late-afternoon peak, riders experienced longer waits and crowded platforms as they sought alternatives. Those headed to or from the Ouchy side faced the most noticeable impact, while travelers on other parts of the line were advised to expect minor delays. Many commuters redirected to walking routes along the lakefront, other bus or tram options, or used the replacement bus service as a direct link between Ouchy-Olympique and Bessières.
Replacement buses and travel tips
To keep people moving, TL set up a replacement bus service between Ouchy-Olympique and Bessières. Buses are operating at regular intervals to mirror the interrupted metro connection, but travelers should anticipate longer journey times and possible detours during peak periods. TL emphasizes checking real-time updates through its app and website, as well as local transit information channels, to stay informed about schedules and any adjustments to the bus replacements.
How long will it last and what comes next
Officials say safety is the priority, and the fault will be fully investigated before normal service resumes on the affected segment. While a precise restoration time has not been published, the aim is to restore service as soon as possible while ensuring the issue is addressed thoroughly. In the meantime, the rest of the M2 line operates, with buses absorbing the demand on the Ouchy-Olympique to Bessières link.
What riders should know
Riders should plan for disruptions and build extra travel time into their journeys during the replacement period. Real-time updates are essential, and those with mobility needs are encouraged to seek on-site assistance from TL staff or call centers. For some, alternative routes via other TL lines or regional buses may offer faster options depending on their destination. The episode underscores the importance of reliable contingency planning and clear communication from transit operators during outages.
Context: Lausanne’s M2 and daily life
Lausanne’s driverless M2 line has become a backbone of city life, linking lakefront neighborhoods with the core of the city and its rail connections. Disruptions like this test the system’s resilience, but TL reiterates that safety, reliability, and rapid recovery of service remain the guiding priorities. Passengers are urged to monitor updates and remain flexible as the network works to minimize the impact of this outage on the broader urban commute.
