I talked to someone a long time ago and they said that the "City of Las Vegas" was a very popular train on Friday nights out of Los Angeles (Gamblers, Hookers (OOps Women)) and Return on Sunday Nights. Same thing from San Francisco to Reno. I don't think the train carried THAT MANY people and they only had one making the round trip so although it may have been one of the 4 trips it probably wasn't all of them.
