Jordan Brinkman, 33, of Walnut Creek was struck and killed by a train at Watkins Avenue in Atherton around 9:30 p.m. Thursday.
None of the 518 people on board southbound Caltrain 192 was injured, according to Caltrain spokeswoman Christine Dunn.
Mr. Brinkman was on foot when he was struck, Ms. Dunn said.
The train was moved to the Menlo Park station so the passengers could board another train, she said. Trains do not stop in Atherton on weekdays.
Samtrans buses carried passengers between Menlo Park and Redwood City stations.
About midnight the northbound tracks were reopened for trains traveling at reduced speed.
This is the fifth fatality on the Caltrain right of way this year, Ms. Dunn said, correcting an earlier error that referred to it as the sixth. Last year there were 13 fatalities.
