This document summarizes issues with Muni Metro's train control system and plans to upgrade it. The current system is over 20 years old and regularly experiences delays and congestion. It discusses the main causes of delays including train control failures, vehicle breakdowns, and congestion. The presentation outlines a plan to upgrade to a new Communications Based Train Control system over several phases from 2023-2029. This will improve reliability, capacity, and reduce delays by integrating train control with traffic signals and allowing better management of train spacing and speeds. Next steps include developing a train control upgrade strategy and two-year plan to improve subway service in the short term.
