Tracks in the Sky: Overhead Lines Then and Now
By Jeremy Menzies
After telling you about the Track Department through the years, this month we take a look back at the Overhead Line Department. The focus of this group is to maintain our “tracks in the sky” which provide electric power to the LRVs, historic streetcars and trolley buses that are critical to keeping San Francisco moving.
SF Municipal Railway Tower Truck No. 1 on Van Ness Avenue circa 1917.
The earliest overhead transit power lines were built for San Francisco’s first electric streetcar line, which opened in 1892. As more electric streetcar lines came into service over the years, the electric grid above them expanded into a complex network requiring more power and more maintenance. Within 20 years, electric streetcars provided nearly all transit in the city.

In the late 1940s, many of the city’s streetcar lines were replaced by electric trolley buses. While they were able to tap into the existing power supply system, these buses made it necessary to expand the overhead line system further. Unlike streetcars, trolley buses need two wires to run, so all the new trolley routes required new overhead equipment.

In addition to wires, the department maintains and repairs all the auxiliary equipment that allows streetcars, LRVs and trolley buses to intersect and make turns, including switches, crossings and breakers.

Emergency response has always been another important and difficult part of the job. Without a power line, trolley buses and subway trains are stopped dead in their tracks. So a speedy response is essential.

Over the years, the department has improved equipment and practices, but inspecting and maintaining the lines remains at the core of its work. Preventative maintenance like stringing new sections of wire in problem areas have played a critical role in improving system reliability.
So we look to the Overhead Line team to make sure the equipment above keeps everything rolling on the tracks and the streets.

Discounted Muni Fares Support the Community
By Emmett Nelson
Find out if you qualify for discounts below.
Did you know that the SFMTA offers a number of discounted fares for our riders? From youth to seniors to people with low incomes, there are options to fit a variety of needs.
For adult riders whose income is at or below 200% of the Federal Poverty Limit, the SFMTA offers 50% discounts on single ride fares and monthly passes. The single ride fare discount can also be used on most Bay Area transit, including BART and Caltrain, at a discount of 20% or 50%. Please visit the Clipper START webpage for more information about the discounts provided at other transit agencies.
In 2013, the SFMTA began offering Free Muni rides for youth in San Francisco from median to low-income households. The Free Muni Program then expanded to include San Francisco seniors and people with disabilities.
In 2021, SFMTA expanded the Youth Program to make it free for all young people, regardless of income or residency. Youth are now no longer required to have proof of payment – they can simply get on and ride.
The latest SFMTA discount fare is the Access Pass, which provides free rides to people experiencing homelessness. The Access Pass is only available to those who are actively engaged with San Francisco’s Department of Homelessness and Supportive Housing (HSH).
To learn more, visit the Fares webpage (SFMTA.com/Fares).
