SacRT understands that these temporary light rail closures can be frustrating for riders. We recognize the inconvenience and appreciate our customers’ patience as we modernize the system to support the new Siemens S700 low‑floor trains. These upgrades will make the system significantly more accessible, reliable, and safer for decades to come.

During each closure, SacRT operates robust bus bridges to keep riders connected. Shuttle buses run during all hours that light rail normally operates, staffed with personnel at key stations to assist with wayfinding and transfers. While buses help riders move through the construction zone, they operate in mixed traffic and carry fewer passengers than trains, which may increase travel time. Riders are encouraged to allow extra time when closures are in effect.

Blue Line construction is more complex than earlier Gold Line work. All Blue Line stations must be upgraded for future three‑car trains, which requires substantially more demolition and reconstruction. Many Blue Line stations also have limited construction access due to adjacent Union Pacific Railroad tracks and surrounding buildings. Because contractors cannot safely stage equipment while trains are running, certain work can only be completed when rail service is temporarily paused.

Even with these challenges, SacRT is using one of the fastest construction schedules in the industry. Multiple stations are upgraded within single 15‑ to 21‑day windows—far shorter than major shutdowns used by other transit systems. For example, Los Angeles Metro’s Blue Line modernization required closures lasting up to nine months. SacRT intentionally designed its schedule to avoid long-term disruptions and minimize impacts to riders.
