Milan's authorities are investigating the recent tram derailment that occurred in a central street, focusing specifically on the tram's automatic braking system, known as the 'dead man's switch.' This safety device is intended to activate and stop the tram in case the driver experiences a health emergency. The tram driver had previously reported feeling unwell, leading investigators to scrutinize the circumstances surrounding the incident that resulted in casualties.

The authorities have initiated checks on the Tramlink vehicle from line 9, which is a modern tram that was seized immediately after the accident for examination. Prosecutor Elisa Calanducci, along with prosecutor Marcello Viola, is analyzing preliminary data and is expected to formally register the tram driver, a 60-year-old individual with over three decades of experience at the transportation company ATM, within the coming days. This phase of the investigation is crucial to determining whether any technical failures contributed to the tragic event.

The incident has raised concerns about public safety and the reliability of modern transport systems. With two fatalities and numerous injuries resulting from the tram derailment, the findings of this investigation will be closely watched by the public and may lead to implications for transit safety regulations in Milan and beyond. Stakeholders and transportation authorities are likely to face heightened scrutiny as the investigation progresses and recommendations are made regarding necessary safety improvements.
