SEPTA regional trains were moving at slightly reduced speeds Friday in response to the extreme heat.
Just like people, the rail lines have to adjust to the dramatic change in temperatures from the summer’s first heat wave, according to SEPTA spokesman Andrew Busch. That includes the tracks and overhead power lines.
The power lines “can sag down in the heat — and this is just the heat pounding down on it,” he explained. “They’re expanding as a result of the heat.”
Busch says the reduced speeds of 5 to 10 mph should not significantly affect travelers. The slight slow-down is expected to continue as long as the heat wave, which is expected to stretch into Saturday and perhaps Sunday.
Riders will also see SEPTA employees throughout the system keeping an eye out for heat-related issues.
Perhaps most importantly for travelers, the air conditioning will be kept in good repair on all SEPTA vehicles, Busch said.
