BART resumed normal service on Saturday morning after an equipment problem led to a partial Interruption on Friday evening.

The equipment issue affected service between Ashby, West Oakland, Rockridge and Lake Merritt stations. According to BART, the equipment issue was located near MacArthur Station.

BART said repairs were made overnight. Although service has been restored, trains may operate at lower speeds due to wet weather.

Friday was the second time in a week that Equipment problems near MacArthur Station affected service in the East Bay.

Smoke on an eastbound train at MacArthur Station forced passengers to be evacuated from the vehicle, resulting in a brief closure of the station and two hours of significant delay as San Francisco-bound trains had to turn around before MacArthur.

According to BART, the problem was caused by a sliding contact (a piece of equipment on each car) interfering with the power rail. The interference could cause smoke and probably arcing.
