Final Update 4:00 p.m.: Repairs to the overhead power supply system at Southwest Museum Station have been completed. Metro Gold Line is resuming normal operations with residual delays to some trips through 4:30 p.m.

The Gold Line is currently experiencing major delays between Pasadena and Union Station due to an ongoing power issue near Southwest Museum Station that began at approximately 11:30 a.m. this morning. Part of the line’s overhead power supply system is damaged at the South West Museum crossover, requiring temporary suspension of Gold Line service between Highland Park and Chinatown Station.

All trains are currently returning north to Sierra Madre Villa at Highland Park Station, and south to Union Station/East LA at Chinatown. Metro is providing shuttle buses to replace Gold Line service between Chinatown and Highland Park. Delays may continue throughout evening rush hour.

The cause of the power system damage is currently under investigation. Metro will provide updates on this incident as they become available, and would like to thank Gold Line customers for their patience this afternoon.
