Yesterday, 19Oct06, one of these trains developed a "brake on in propulsion" somewhere around the Bayfair Station. The operator went back to find the culprit car, and found it. The error reported by the car was "locked axle fault" on axle #2. Car was cut out, as appropriate for such events. A tech met the train soon thereafter, and heard a grinding noise from under the car. He reported the train should not be in service, yet Central Command refused to take the train out of service.
At 19th St Station, another tech got on, and reported the same. At El Cerrito Plaza Station, suddenly the car developed MAJOR flat spots, as reported by the tech, and then the flats just as quickly seemed to disappear. What was occuring was the gear box for the axle locked, and the train was pulling the car with the wheels on that axle not rotating, grinding the wheel down. The gearbox released, which was the sudden occurance (sp?) of flats, then locked up again (the flats disappeared). Finally at El Cerrito Del Norte, the train was removed from service, and moved .s.l.o.w.l.y., at 5 MPH to the Richmond Yard/Shop.
