Atlanta Trolleybus History: The Rise and Fall of Electric Transit
Before the dominance of the modern diesel bus, Atlanta's streets were defined by a sophisticated network of electric transit. The transition from traditional streetcars to trolleybuses—electric buses that draw power from overhead wires—marked a pivotal era in the city's urban development, blending the efficiency of electric power with the flexibility of rubber tires.
The Origins of Electric Bus Transit
The shift toward rubber-tired transit in Atlanta began in 1925, when some streetcar lines were first converted to gasoline-powered motor buses. However, the true era of the trolleybus began in 1937. On June 28, 1937, the city launched its first trolleybus route, serving the suburbs of East Point with additional branches reaching College Park and Hapeville.
A second route followed in 1940, and the process of converting streetcar lines to electric buses continued steadily until the final streetcar line was closed in 1949.

Growth and Operational Peak
By 1950, the trolleybus system had become the backbone of Atlanta's transit. At that time, 453 trolleybuses operated across 31 routes. While these vehicles made up 70% of the total fleet, they were remarkably efficient, carrying 80% of the system's total ridership.
Ownership Transitions
Until June 1950, the system was owned and operated by the Georgia Power Company. Following this, ownership transferred to a group of local businessmen who established the Atlanta Transit Company (ATC). Under ATC management, the electric network remained largely intact for another decade.
Innovative Express Services
One of the most distinctive features of Atlanta's system was its express operation, a rarity for trolleybus networks. To facilitate this, eight routes were equipped with 250-foot (76 m) sidings—special sections of overhead wiring that allowed express vehicles to bypass local buses stopped at stations.
Expansion continued through the 1950s and early 1960s. In November 1956, bus line 26-Perry Homes was converted to trolleybus service, with further extensions added in 1960 and 1962. By the end of 1962, the network had grown to 39 routes.

The Decline and Closure of the System
Despite its success, the trolleybus system faced insurmountable logistical and financial hurdles by late 1962. The Atlanta Transit Company decided to phase out the service to avoid the high costs associated with installing new overhead wires whenever routes were extended into new areas.
Furthermore, the fleet was aging, with vehicles ranging from 14 to 17 years old. Replacing them proved difficult because no North American manufacturers were producing trolleybuses at the time; Marmon-Herrington, a key producer, had ceased production in 1959.
The end came swiftly in 1963. At the start of the year, 273 trolleybuses remained active. In September 1963, the entire electric system was converted to diesel buses in less than a month. The final trolleybus service in Atlanta operated on the night of September 27, 1963.

Frequently Asked Questions
Why did Atlanta switch from streetcars to trolleybuses?
The city began converting streetcar lines to trolleybuses starting in 1937 to modernize the fleet while maintaining electric power, eventually replacing all streetcars by 1949.
What made Atlanta's trolleybus system unusual?
Atlanta implemented express services on eight of its routes, using 250-foot overhead wire sidings to allow express buses to overtake local buses.
Why was the trolleybus system eventually shut down?
The system was closed to avoid the expense of installing new overhead wires for route extensions and because of the difficulty in sourcing new vehicles after North American production ceased.
Who operated the transit system before the Atlanta Transit Company?
The system was owned and operated by the Georgia Power Company until June 1950.
How quickly was the transition to diesel buses completed?
The transition was remarkably rapid, with the entire electric system being converted to diesel buses in less than one month during September 1963.
