Riding on the edge. Amtrak 458 (EMD F59PHI) trails next to the Webb Rail LLC - WEBX observation/lounge/sleeper former New York Central "Babbling Brook" on Sunday, August 20, 2017 as it hugs the cliff while passing Sunset Seat in Del Mar, California. The car is riding Train 768, and as such had to ride behind the engine as all Pacific Surfliner trains have controls at each end. While the "Babbling Brook" remains with Webb Rail, Amtrak 458 has since been sold to METRA in Chicago, IL to continue its career.
