Four metro trains on line M2 in Bucharest are returning to service to alleviate congestion during peak hours. These CAF trains will be deployed in special situations to manage high passenger volumes, particularly at Piata Unirii 2. Since September, waiting times have nearly doubled due to other trains undergoing maintenance. The M2 line, known as the "Corporate Line," serves around 200,000 passengers daily and has not seen significant investment since its opening in 1986. The return of these trains is expected to improve service frequency for commuters.
