Unions representing workers at Atm have called for a new extraordinary maintenance plan after a concerning string of incidents involving trams, which have escalated to four accidents in just 13 days. The latest incident occurred on the tram line 27 in the Mecenate area, where the wear and tear of a cable caused a small fire after it broke. This incident has raised alarms regarding the adequacy of existing maintenance protocols at Atm, particularly given the recent severity and frequency of such events.

The incidents vary in nature, including a loose bolt on the track and a tram that derailed when a wheel slid off the rails due to an obstacle. However, the situation escalated significantly with a tragic accident on February 27, where tram 9 derailed due to a medical emergency involving the driver, leading to the unfortunate deaths of two passengers and injuries to others. These incidents underline the potential dangers of neglect in regular maintenance and inspections, prompting unions to advocate for immediate remedial action from Atm's management.

The requested extraordinary maintenance plan aims to address these issues comprehensively, ensuring the safety of both passengers and staff. It reflects a broader concern for infrastructure safety within Italy's public transportation systems, highlighting the critical need for ongoing and rigorous evaluation of maintenance strategies to prevent future incidents. With union pressure mounting, it remains to be seen how Atm's management will respond and what measures they will implement to enhance safety protocols.
