Cracks in Central Park West track disrupt NYC subway service and trigger emergency repairs

Cracks found under the trackbed at Central Park West trigger emergency repairs, halting local downtown service on the A, B, C, and D lines from 125th Street to 59th Street–Columbus Circle. B and C trains run express downtown, while crews work around the clock on a temporary fix with permanent repairs planned for a later date; uptown service is affected by delays and there’s no clear completion time yet.
