BART service was suspended between the Hayward and Fremont stations due to an equipment problem on the tracks, first reported around 1:30 p.m. on Friday. The South Hayward and Union City stations are closed while crews address the issue, with southbound trains turning around at Hayward. Riders have been advised to use AC Transit buses for service between the affected stations at no charge. Meanwhile, BART had also suspended its Orange Line service between Bay Fair and Berryessa earlier in the morning, but regular service was restored shortly thereafter without a disclosed reason for the suspension. The transit agency is still managing delays and disruptions as they troubleshoot the ongoing equipment issues.
