Rome: The Metro B station at Rome’s central Stazione Termini was evacuated after smoke began seeping out onto the tracks, according to Italian news reports.
There was nobody injured in the incident which occurred during the free public transport day as part of the city’s events to mark European Mobility Week.
The capital’s public transport company ATAC laid on substitute buses to serve the metro line overground as firefighters investigated the cause of the smoke.
The fumes are not believed to have been caused by a fire, Italian media reports, and the metro resumed its regular service in the late afternoon.
The subway evacuation is the latest in a series of high-profile incidents to affect Rome’s public transport network this week, including dozens of commuters being locked inside Cornelia metro station during a public transport strike on Friday.
