What is the most distinctly Philadelphia way to travel around our city? Is it perhaps the trackless trolley?

You may know it by another name: the trolley bus. They’re essentially buses that connect to wires above the street, drawing on electricity for power.

A Philly manufacturer began road-testing this technology back in 1921, sparking the Evening Public Ledger headline:

“Trackless Trolley Has Secret Debut in Philadelphia.”

1921 Evening Public Ledger article on the trackless trolley’s “secret debut.”

For decades, J.G. Brill Company operated a massive trolley factory in Southwest Philly. At one point, it was among the nation’s largest producers of trolley cars. The trolley bus was part of its repertoire.

In 1923, two years after the so-called secret tests, the trolley bus made its official debut on city streets.

The first route ran along Oregon Avenue in South Philadelphia, and curious Philadelphians clamored to take a “joy ride,” as described The Inquirer at the time.

There wasn’t even an actual transit schedule that first day. Officials just ran cars so that people could experience the thrill.

Philly was an early adopter of the trackless trolley. And it had its advantages. The vehicles are quieter and greener than other buses.

But trackless trolleys generally lost the race against their diesel-powered brethren.

Only a small handful of American cities still run them.

And one of those cities is…Philadelphia.

If you don’t venture to North or Northeast Philly you might not be aware that SEPTA still has a few circulating.

That means Philadelphia has been in the trolley bus game for a century.

In fact, Philly has the longest-running trolley bus service in the entire hemisphere. Only Shanghai, China, has been doing it longer.
