Depending on how you define it, 200+ might be overkill, but I think that "clock" service on most of the major routes and significant north-south connectivity without forcing a mode shift (namely plugging the hole with buses). The main problem, at present, is that you have two ways to do that and both involve major time-killers (Tehachapi Pass is beautiful but slow, and so is the Coast Line). A pair of north-south overnight trains (one on each line) would be nice. But it's got practical issues in both cases. I guess the question is what the economics of a "baseline" overnight train with a significant complement of sleepers (the Spirit of California was notably mis-equipped...it had two sleepers that apparently had a tendency to sell out and a batch of coaches that went empty for much of the route; anecdotally, the train seems to have needed another few sleepers since there are only so many pax who are going to willingly go overnight in an Amfleet I) and a cafe.
