Due to shifting track because of tides affected by the Florida hurricane all service is suspended
On the West Coast? From the reported surge? That makes little sense to me.
Bet it’s Kay, not Ian…
From the San Diego Union-Tribune:
The print ersion of the article had a 2021 picture of a Metrolink train that was apparently stopped by high waves, possibly in conjunction with a high tide. The article mentioned the settling was on a 700’ long segment and the amount of settling was a small fraction of an inch. Amtrak and Metrolink service was halted out of an abundance of caution.
The article mentioned that 20,000 tons of rip rap have been placed recently to protect the tracks from waves. I don’t think the salt spray does much good for the functioning of the track circuits.
How was Santa Fe able to run this line for 100 years with few delays yet the Gov’t agency is all but shutting down the line for 60 days?
The Climate wasn’t changing when ATSF operated the line. Climate change and the increase in global temperatures are melting glaciers all over the globe - the water that is melted out of the glaciers ends up in the oceans and thus raise the level of the oceans.
Is the sea rising, or is the land subsiding?
San Juan Cap/ Laguna Nigel all the way down to Oceanside had issues while it was Santa Fe owned it. They had resources that the quasi-government agencies did not have to throw at the problems, including people who had a vested interest in protecting “the property”. Not that way anymore. Hardly a new problem and the local geology/ soils are nasty & expansive when they get wet / can’t drain. Laid new steel and ties down there before turning over the plant to the Lossan/San Diego Trolley/SanDag/MetroJoke people.
It’s California being its abnormal weird self.
I believe it is both, when they talk about restoring beaches to protect this coast line I believe they are also pointing to previous storms carried away the beaches which protected this coast specifically.
With the rising Ocean level they are going to need to replace this line entirely building it up with rip-rap is just a band aid.
There was a guy in another forum in North Texas here saying what babies people are that can’t live without AC here in Dallas after almost a month of temps 100 degrees or more. I looked back 55 years “when he was growing up” and allegedly tolerated it. Could not find a 30 day block of near or over 100 degree temps. In fact the temps were a LOT cooler in his child hood. He never thought of making that comparison himself using weather data before publishing something dumb.

That part of the California coast has become intensely developed. Rooftops, parking lots, roads, and other hardscapes, along with stormwater management affect rain infiltration and its influence on erosion. Also that region is very tectonically active with things that are less noticable like land uplift/subsidence and submarine landslides. All in addition to expected coastal erosion.
Most of the coastline in this part of SoCal is either sandstone (cliffs) or sand bars, neither of which is very resistant to erosion. In the time I’ve lived in Encinitas, there have been at least two cliff collapses that resulted in fatalities. The victims were sitting or laying on the beach and got buried by the maerial falling off the cliff. One contributing factor is poor drainage of the ground at the top of the cliff. (I’m quite sure MC already knows this, just amplifying what he wrote.)
One other problem with the San Juan Cap segment is that it is now the longest stretch of single track on the LOSSAN line and has been the source of many delays waiting for the track to clear.
From today’s paper, another story:
So, based on the following quote from the article, the max movement could amount to 3.7 to 14.6 inches or so over a year. Maybe our muddy feathered friend could comment on that.
“Geologists and engineers monitoring the slide area detected new movement at the rate of 0.01 inch to 0.04 inch per day after another storm last month.”
…and you expect that to move uniformly, evenly and all in the same direction?[^o)][swg][:^)]
I’ll own up to the bolded part, for sure. I’m no dirt engineer, but I do see a lot of people out and about with stations measuring the streets. “Comes with the territory,” you could say. Mind you, I live in a neighborhood that had a few houses slide away forty or so years ago, and we are at east 15 miles inland.
I’m reminded of a cartoon that was on the bulletin board outside the soils lab which showed an Italian developer doing a presentation and showing a chart of a perfectly vertical Tower of Pisa, explaining, “We gonna save a 5,000 lira by not doing soils testing.” I still chuckle at it after 45 years, probably because I hear the statement in Father Guido Sarducci’s voice.
San Francisco has its own “leaning tower”.
I’d be prepared to say that it’s likely the ‘geologists and engineers’ are measuring movement in one plane, a direction of observed ‘slip’ (probably toward the ocean). What would be highly interesting to see, and I’d be prepared to say it exists, is a graph of actual slip day by day for the past several years, with an indication of actual cumulative slip within longer periods, ideally correlated with weather or other events. If it does not exist yet, it could probably be plotted quickly from the ‘detected new movement’ data that have been ‘recorded’…
I’d be more interested to see the periodic maintenance of line and surface in this ‘slide area’, if the cumulative slip at the ‘new movement’ reported rate is characteristic at any prior time, or ongoing…

More like “heat island effect” than global/climate/cooling/warming/change.etc. More people, more glass, more asphalt, more concrete.
No other place to move the line to…unless you want to deal with more up and down grades and NIMBY and BANANA. This line replaced the original SF line through Temecula Canyon that had continuous washouts.
