San Francisco Municipal Transportation Agency is now testing Muni trains in the yet-to-be completed Central Subway Project. 

The Central Subway Project will extend the T-Third Line light rail through downtown to SoMa, Union Square Chinatown. 

The new line has been under construction for nearly a decade and is set to open by spring of 2022. There has been much criticism over the line for construction delays and for being over budget.
