On June 5, 2025, a massive fire broke out at SEPTA’s Midvale Depot in Philadelphia, destroying 40 out-of-service buses. Speculation swirled—was it arson, a setup, or just bad luck? Now we know: the fire started in an electric bus. And it’s not the first time a Proterra bus has ignited in Philadelphia. Back in 2022, a similar bus caught fire while charging at SEPTA’s Southern Depot. That incident led to a national recall, but no fix was in place.
