Passengers are advised to allow extra travel time today as maintenance crews continue to work to resolve a loss of traction power in the Highland Park to Pasadena area. Gold Line trains are running every 30 minutes from Altadena to East Los Angeles. Take note to board on the north to Pasadena track at Highland Park, Mission and Fillmore stations as trains must use the northbound track to single track at reduced speed through that area. The loss of traction power de-energized tracks between Southwest Museum and Del Mar stations at 9:30 p.m. Saturday night.
