SAN FRANCISCO (CBS SF) – A trackside problem on the Bay Area Rapid Transit system in San Francisco has been repaired Monday morning, a spokesman said, though trains were still running at least 10 minutes behind schedule.

The trackside mechanical problem occurred between the Embarcadero and Montgomery stations beginning at about 5:45 a.m., BART spokesman Linton Johnson said.

Trains were single-tracked through the area until repairs were made at about 6:30 a.m., Johnson said.

All scheduled San Francisco-bound trains were in operation as of 6:45 a.m.

Monday’s delays follow a derailment Sunday which injured three passengers and damaged BART cars and tracks in Concord.  Service on the Bay Point/Pittsburg line was disrupted until repairs were completed early Monday morning.
