On Saturday, October 19, 2013, at 1:44 p.m. Pacific daylight time, Bay Area Rapid Transit District (BART) train 963 struck and killed two engineering employees while they were working on BART’s main tracks near Walnut Creek, California. The train, which included four passenger cars, was travelling north on the Pittsburgh/Bay Point-SFO (San Francisco International Airport) Line between the Walnut Creek and Pleasant Hill stations. It was one of two trains being operated by BART managers because BART’s union employees were on strike. Both trains were transporting management employees, who were being trained as substitute operators and system maintenance workers. No paying passengers were being transported by either train.
