Amtrak alerts noted on the map at [
asm.transitdocs.com] for Surfliner trains indicate the track closures between Fullerton and LA are still in effect. Must have been a serious power line situation, not sure why no local news coverage. Anyway, Surfliners continue with bustitution between LA-Fullerton for this morning's trains.
And just to add more confusion, yesterday's #4 is operating very late due to a trespasser incident with a commuter train ahead of it on Metrolink blocking the line yesterday.
