SF Muni – San Francisco Municipal Railway

The San Francisco Municipal Railway (SF Muni) is the public transit system for the city and county of San Francisco, California. Muni is the seventh largest transit system in the United States, and the second largest in California.

Muni is an integral part of public transit in the city of San Francisco, operating 365 days a year and connecting with regional transportation services, such as Bay Area Rapid Transit (BART), SamTrans, and AC Transit. Its network consists of 54 bus lines, 17 trolley bus lines, 7 light rail lines that operate above ground and in the City’s subway tube.

Battery backup systems are critical to the safety and continuous operation of Muni’s extensive transit system. Muni uses Global Energy Innovations’ EC2000™ Handheld Battery Analyzers and IBMS™ to monitor the health of it’s battery backup system to prevent costly downtime in the event of a power outage.
