SAN FRANCISCO (KRON) — The cause of a 10-inch crack in a BART rain in San Francisco remains under investigation.
The crack caused 6-hours of major delays system wide last week.
The average life span of BART rain is about 35 years, but the section that cracked in San Francisco was only a few years old.
That crack was actually spotted by a train operation who thought he saw something and went slowly through the area, spotting the large crack.
That’s exactly what BART officials say that should reflect the system’s overall attention to safety.
BART spokesperson Jim Allison says the transit agency will know more about exactly what happened when the track testing results are completed in a few weeks.
