From 1969 to 1985, the Pacific Locomotive Association had its railway museum at Point Molate and was a very popular weekend destination. The boarding area was located where Point Molate Beach Park is now.  The Pacific Locomotive Association operations are now located at Niles Canyon. See https://www.youtube.com/watch?v=ZsZ_mnJRlsE.
