Caltrain returned to its full weekend service schedule Sunday morning, three days after one of its trains slammed into several vehicles in a fiery crash that left 13 people injured.

The announcement by Caltrain ends days of significant delays to train service throughout the Peninsula, as crews worked to clear wreckage of Thursday’s crash from the tracks near Scott Street in San Bruno. The agency had been running 69 trains instead of its regular 104-train schedule, with SamTrans providing bus-bridge service between the South San Francisco and Millbrae stations.

The National Transportation Safety Board is investigating the fiery crash. It happened just before 10:40 a.m. Thursday when southbound train #506 collided with a line of construction vehicles consisting of one pickup truck and two flatbed trucks with cranes.

The train operator, four train passengers and the driver of the electrification vehicle were taken to a hospital, and are expected to survive. Another seven people were treated at the scene.

The train was traveling 60 mph, which is 19 under the maximum speed limit, when the crash happened, according to NTSB Vice Chairman Bruce Landsberg. The train operator applied full braking and blew the horn to warn the construction workers, who appeared to have only a “few seconds,” to get out of the way, Landsberg said.
