On November 16, the MBTA presented an updated analysis of its State of Good Repair (SGR) Index, which measures the Authority’s capital asset needs, to the Board of Directors (here) in which it revised the SGR Index to $24.5 billion from the most recent $10 billion estimate presented  in 2019. The presentation and discussion with the Board raised a bevy of unanswered questions regarding the impact of the new findings to those who follow the Authority’s progress and the implications for a safe and reliable transit system.
