BURLINGAME (CBS SF) — Caltrain service has resumed along the Peninsula after the agency earlier said its trains were halted following a collision in Burlingame.

At 9:32 a.m. the agency tweeted the southbound SB504 train “has been involved in an alleged incident at Bayshore.”

As of 11:01 a.m., Caltrain was reporting major delays systemwide.

Last month, a Caltrain crashed into maintenance vehicles on the tracks in San Bruno, sparking a large fire in one passenger car and injuring 14 people. Earlier this month, a preliminary NTSB report said a Caltrain worker notified dispatchers that the tracks were clear of the maintenance crew minutes before a five-car commuter train traveling at 65 mph slammed into their vehicles.
