The chief disaster on the SD&AE was, and probably is, the tunnels. They all have to be opened up to modern clearances and then properly lined and portaled so further caving-in is prevented.
Then you can take up the issue of other erosion on the embankments, which in my opinion should be addressed with geotextile. I don't know what needs to be done with the viaducts and bridges, but I think it's been discussed.
Just as with Canada, if you have locked and secured COFC/TOFC I think something could be worked out with Mexico for the actual international running. But you'd still need some way to keep people from jumping on the train and 'riding the rods' across the border... drones and dogs and sensors, oh my!
Erik_Mag Unless the SD&AE line has been re-opened, the answer is that they don't. Freight will have to be trucked in or out. I have no idea of how long the line will be closed, could be a few days or possibly up to a few months.

Fred M CainI think that if sufficient rip-rap was dumped in there, they'd probably be able to reopen the line long enough to seek a more permanent fix.
The slide issue is far more important, and no amount of riprap will address it. Even slope remediation, or the usual sorts of stabilization like bracing or geotextiles, are impossible for 'ecologically' based reasons or concerns. The only method short of the radical line realignments that have been discussed (look at a topo map if you need to understand what is involved in new alignments) is to elevate the section through San Clemente in a way that keeps it 'well above the waves' while permitting locals easy access across the ROW... that pretty much means an esthetically-designed viaduct, and to elevate the areas in the 'slide' regions so that any slips don't block the track or damage its alignment... again, that would probably indicate some type of viaduct.
That sort of project won't work without using some form of self-launching construction, probably with the necessary piers designed like 'cutwaters on steroids' immediately adjacent to the existing track to facilitate access to placing the supports and foundations for the self-launching equipment. This simplifies keeping current operations fluid and at least making staging and provisioning of the precast elements doable.
One plan was suggested to completely relocate the line on an alignment further east near I-5. SHEESH ~ ! The way the government does things, that's probably take years.
Overmod azrail I don't know if there is a way to totally fix the problem. There is no other place to relocate the line. The only real 'solution' that doesn't involve the usual showstoppers 'as much' is to elevate the line on Chinese-style self-launched viaduct construction. Wishfully thinking, this could be done esthetically enough not to create the usual Harbor Freeway waterfront disaster. And it might have inherent electrification provisions in its construction...

I just can't help but wonder how all this would've panned out had BNSF still actually owned the line. My guess is that if it were important to them, they would've had it at least somewhat repaired and up and running in a few days.
A couple of years ago there was a bad forest fire in the northern part of the state that took out some major bridges. Although that is a different situation, there were predictions that the line would be closed for at least a month or so if not longer. The YouPee had it up and running in a few days.
That's the way private businesses do business.

Yes, but all traffic was halted through the slide area this time.
Did see frequent Coaster service tis afternoon attending the Encinitas street fair.
Didn't some freight trains continue to run while passenger service was halted at the land slip/stabilization project site a little bit further down the line to the south?
They need to go surfin with that train.......

They don't.
The slides have been an issue for generations and are beyond the railroad's control. The problem starts well off the R/W.
How does BNSF route freight into/outof San Diego with the surf line temporary closed?
