2 firefighters injured battling fire in West Philadelphia

Underground cables overheated and caught fire, causing a manhole cover to explode, cutting power for two blocks.

Preliminary investigations found the pilot’s black box recorder did not record audio from the Jan. 31 flight and likely hadn’t worked in years.

SEPTA said it initially will run eight buses with the compartments to see what, if any, adjustments are needed and to get driver feedback.
