The main Train Route has been closed due to Alisal Fire too

 So, not only has 101 been closed but also the train tracks for the Amtrak that runs up and down the coast there too. 

Here is the Amtrak line closed. (They likely are using buses to take people between San Luis Obsipo and Los Angeles and San Diego).

I have been to the Santa Barbara train station many times to pick up or put friends or relatives on the train there. But, I'm not sure if there is still service from Santa Barbara to Los Angeles or San Diego right now or not.

Pacific Surfliner[edit]

Main article: Pacific Surfliner

The Pacific Surfliner serves Southern California on a route between San Luis Obispo and San Diego via Los Angeles; most trains only travel a portion of the route. It hugs the California coast for most of the route – coming as close as 100 ft (30 m) – providing views of the Pacific Ocean. With 2.7 million passengers in fiscal year 2013, it is Amtrak California's most heavily used service and the most used Amtrak service outside the Northeast Corridor,^[4] behind only the Northeast Regional and the Acela Express.^[5] It is also the oldest, dating to 1939 with the Santa Fe's San Diegan.
