Two veteran workers on the Washington area's transit system were struck and killed by a maintenance truck while working on a track Tuesday, the latest in a string of fatalities on the Metro system since last year.
Jeff Garrard and Sung Oh were installing safety equipment on a track that was closed to regular service for the night when they were hit. One of them died at the scene--the other, on the way to a hospital.
Metro says both men lived in Montgomery County, Maryland. Garrard had worked for Metro since 1990, and Oh had worked there since 1998. The accident comes two weeks after Metro held a three-day workshop on track safety with experts from around the country.
The National Transportation Safety Board is investigating what happened.
