The Rail Authority published the Preliminary Alternatives Report for its proposed L.A. to San Diego line. Previously, it had announced that the report was ready but did not actually post it. I have not read it yet but intend to read it tomorrow and post an analysis on Wednesday. The Rail Authority Board will meet on Thursday in downtown L.A. to discuss and approve the report.
UPDATE: The report says exactly what we already expected. The routes along the I-10 freeway and SR-60 will continue to be studied, while the routes that use and run adjacent to the Union Pacific railroad are withdrawn and will not be studied.
