Daily Coast Daylight train along one of the seaside sections of the line.
Southern Pacific's Coast Daylight route was originally introduced as the Daylight Limited on April 28, 1922 and ran until May 19, 1974 and covers 471 miles between Los Angeles and San Francisco. The line saw streamlined steam power between March 21, 1937 until January 7, 1955 at which point Southern Pacific replaced it's GS-4s with ALCO PAs and EMD E7. Amtrak took over the line on May 1, 1971, renamed it the Coast Starlight and extended the line from Los Angeles, California to Seattle, Washington.
Route Highlights
16.5 mile Cuesta Pass between Santa Margarita and San Luis Obispo. Which has seven tunnels, one bridge, 53 tight reverse curves and the famous Goldtree Horseshoe curve all of which is along a 2.2% grade.
113 miles of ocean side track complete with rolling hills and beach front.
Rolling Stock
The line was famous for the GS-2, GS-3 and GS-4s that ran along the route as well as the articulated passenger cars that were common in the Daylight consist.

GS-4
and finally the passenger cars which can be found in greater detail here.

Final Points
I would recommend the route be done during the Golden State era (1937-1955) and come with a complete set of GS-2, GS-3, GS-4 engines as well as the passenger cars for the set. I do understand we have a GS-4 already in TS-2016 but it is outdated and desperately needs to be upgraded to TS-2016 standards (like the UP FEF-3). I also understand that there is no way the whole 471 miles would ever be in one route especially considering it took the actual Coast Daylight around 9 hours to complete the route, I do imagine that the only section that would be modelled would be between Paso Robles and Chatsworth which is roughly 228 miles long and would encompass both Cuesta Pass and the 113 mile long coastal run.
