Caltrain service started to return to normal Monday afternoon after a derailment near Diridon Station in San Jose caused major morning delays, but commuters should expect 10-15-minute slowdowns during the evening commute, officials said.

Caltrans spokesman Alex Eisenhart said a single car that derailed on southbound train 324 at about 9:15 a.m. has been put back on the track, and trains are still steering around the area while the incident is investigated.

The juggling won’t cause problems in midday, he said, but once trains start running more frequently in the late afternoon and evening delays are expected.

No one was injured in the derailment, which took place just short of Platform 4 at Diridon Station, officials said. The crew was able to limp the train into the station, where the train was quickly emptied. Delays as long as 73 minutes lasted through the morning.

Caltrain officials advise checking Twitter and electronic information signs for frequent schedule updates.

Eisenhart said the car that derailed was the last car on the train. One set of train wheels, known as a truck, left the track. He could not specify how many people were aboard or what type of rail car was derailed. He said the car that left the tracks remained standing.

In late February, three Caltrain trains derailed in four days near Diridon station. None of the trains were carrying passengers, and the derailments took place on a stretch of tracks used for maintenance, officials said.

Monday’s derailment occurred on a different stretch of tracks, Eisenhart said.

An investigation into the cause of Monday’s derailment is continuing.

Correction: A previous version of this story transposed the number of derailments in February with the number of days in which the derailments occurred.
