When the bluff finally collapses this will be a national emergency since it is the only rail line to San Diego. A solution may be to build two miles of elevated rail above the ocean to connect the two ends of the track. The water gets deep a short distance from shore, this is possible but very expensive.
Meanwhile, further up the road in the San Joaquin Valley...
...which in the quest for dreams coming true is, apparently, not a "national emergency".
It's just money.
