Three people were struck and killed over the weekend by Amtrak trains that were to pass through Washington or end their run here.

In the first incident, train No. 159, which was to terminate in Washington, struck a trespasser on the tracks in Sharon Hill, Pa., a few miles southwest of Philadelphia, said Amtrak spokesman Marc Magliari. There were 318 people on the train, he said. That train and several others in the northeast corridor were delayed, he said.

In the second incident, two people who were on the tracks were killed near Durham N.C., Sunday about 9:45 a..m. That train, No. 80, is called the Carolinian, Magliari said.

The Carolinian, with 80 people on board, was to end its run in New York. None of the victims was identified.
