Planned extension

The extended section will be long and has 6 stations. Trains will run mostly underground (60%). Although the project was approved in 2010, it was put on hold in early 2011 due to lack of funds. Works were postponed to a later date. Currently there are plans to replace 48 lifts and 52 elevators for the Milan-Cortina Winter Olympics in 2026.
