BART partially restored train service between North Concord and Pittsburg/Bay Point stations on Monday by running a train between the two locations, but cautioned that it could take time for the service to return to normal.
The transport provider said its crews tested a new tool yesterday to measure voltage spikes more precisely. The voltage spikes are currently happening in 100 milliseconds, and the new tool is expected to shed light on the problem that that damaged fifty cars and forced BART to temporarily close tracks between the two stations around a week ago.
BART announced yesterday that it would immediately start operating a train every fifteen minutes between the two stations during peak hours between 3 p.m. and 8 p.m. and between 4 a.m. and 9 a.m. At other hours, the service will revert to the bus bridge that was rushed into duty on Wednesday last week after the electrical problem erupted.
Alicia Trost, a spokesperson for BART, said, “This is an improvement. It gets us back to something like normal service on this line at the busiest time of day. But we still don’t know the root cause of the problem.”
BART’s assistant operations general manager Paul Oversier said the test trains were equipped with high-tech tools to measure data and help pin down the issue but the test runs could not produce desired results.
BART operated a total of 557 cars on Monday. The number was less than normal but 36 more than where it was on last Friday. Officials said it still could take weeks or even months to bring all the damaged cars back into service.
