The Capitol Corridor is a 168-mile (270 km) passenger train route in Northern California operated by Amtrak between San Jose, in the Bay Area, and Auburn, in the Sacramento Valley. The route is named after the two points most trains operate between, San Jose (which hosted the first state capitol of California) and Sacramento (which currently hosts the California State Capitol). The route runs roughly parallel to Interstate 880 and Interstate 80. Some trips run from Oakland to San Jose, while a single daily round trip runs all the way from San Jose to Auburn, in the foothills of the Sierra Nevada. Capitol Corridor trains started in 1991. Map of the Route Why the Capitol Corridor?: The Capitol Corridor is the fourth busiest Amtrak line behind the Pacific Surfliner, Northeast Regional, and Acela Express. The Capitol Corridor is also the second busiest passenger rail line in California; the line had amassed 1,607,277 riders in 2017. A route like this would be perfect for Train Sim World. Along the route are also plenty of industries served by Union Pacific; it's an intriguing challenge to handle a route with not only busy passenger traffic but also freight traffic, both local and long-distance. I figured it would be best to have the route be between San Jose and Sacramento as the line extending to Auburn doesn't see too much passenger traffic; plus, it also saves time. Another reason I feel the Capitol Corridor would be a good addition to Train Sim World is that there can also be the inclusion of preexisting Caltrain consists that can work as AI trains along the tracks from San Jose Diridon to Santa Clara. The same could be applied to the Peninsula Corridor with AI Amtrak trains running along the same segment. Rolling Stock: The main rolling stock for the Capitol Corridor consists of California Cars built by Morrison–Knudsen and the American Passenger Rail Car Company, EMD F59PHIs, and the newer Siemens Charger locomotives. Occasionally, P42DCs have been seen pulling/pushing Capitol Corridor trains. Regarding freight traffic, GP38-2s can do locals, whereas ET44ACs and/or SD70Ms are in charge of long-distance trains.

I'm curious to see what everyone else thinks of this idea!
