A San Diego Trolley car derailed Monday without injuring anyone, but delayed about 5,000 northbound morning commuters from the South Bay, authorities said.
About 300 commuters were aboard the car when its two rear wheels derailed about 7 a.m. just before the Civic Center Drive stop in National City, said Langley C. Powell, president and general manager of San Diego Trolley Inc. The car stopped without overturning, he said.
The trolley was traveling about 15 m.p.h. over a switch when the wheels derailed, Powell said.
The cause of the accident was under investigation Monday, Powell said. He said that the accident was the first over the switch, which was designed for the freight trains that used the track before trolley service began.
Workers cleared the track by 9 a.m. and trolley service resumed, Powell said.
No dollar estimate was given, but Powell said damage to the trolley car was minor.
