METRO RED LINE FINAL UPDATE: Signal repairs completed ahead of schedule; trains resume normal operations to all stations. No further delays.

Previously: Here is the announcement issued by Metro Rail operations:

Passengers riding the Metro Red Line from the San Fernando Valley into Hollywood and downtown Los Angeles should plan on travel time delays until further notice.

Damage to the train signal system tonight will prevent the trains from running at normal speeds. Expect an additional 10-15 minutes of travel time between Universal City and Sunset/Vermont Station. Board trains 20 minutes earlier than normal. Additional trains will be added to the regular service to keep departure times from stations at approximately every 10 minutes.

Metro will issue periodic updates. Follow @metroLAalerts on Twitter.
