It would be really amazing route, showcasing San Jose, Oakland Emeryville, North Bay area, Davis, The Greater Sacramento area, and more. There could also be some BNSF and UP action with the Oakland Port and The Richmond Area. Maybe even the RPR short line railroad in Richmond.
BNSF is just a no. DTG cannot develop BNSF and sell it worldwide, and have themselves personally not done any since 2015. The only BNSF seen is from third-party and is fortunately found in two editions, but DTG refuses to do two versions (at least until South Wales Coastal needed a rebrand, and the Pendolino went to WCMLS in a different livery).
