Timothy Nolan((John Vernon) was lucky. He got to sit with unmarried Katy(Diane Moldaur) on the train, while the rest of the train robbers brandished hardware and dynamite in stopping the train and opening the mail car, to get at the strong box containing paper currency. The latter was stuffed into the empty suitcases of Nolan and Katy, who had no problem getting past security to their hotel room. They would soon marry, buy a mansion and make investments with nearly the whole of the loot. Several years later, Nolan tries to steal a gold shipment from a Chinese mining consortium, but is thwarted. He needs a big loan or heist to avoid bankruptcy before his investments pay dividends. The commercial banks won't make the loan, so he keeps sounding out the Chinese for a loan. They aren't too keen on the idea.......Meanwhile, fellow train robber Harker Fleet(George Peppard) has been sent to prison, not for the train robbery, but for injuring the sheriff and deputy in his haste to exit a window when he heard that he was expected to marry a girl he had made pregnant. Fleet later discovered that the girl wasn't pregnant, although they had married that morning. She soon had the marriage annulled, as she didn't want to be married to a jailbird. Nolan had successfully deprived Fleet of his share of the loot, and had stolen his girl(Katy), who believed him married. Two and a half years later, Fleet was released, and moved to where Nolan and Katy were reported to be. Eventually, Nolan, Fleet, and Chang(head of the Chinese miners consortium) agreed on a complex plan to get the Chinese gold safely to San Francisco. Nolan was hoping to steal part of it. You may need to run this bye again to gain an understanding of the details. Anyway, there is a climactic shootout around the train and train station, the Chinese using dynamite in place of firearms, which they were unfamiliar with. It was Nolan and henchmen vs. Fleet, the Chinese, and Katy. Guess who ends up alive to claim Kate as his wife-to-be.......This is the only western I've encountered where Chinese gold miners are characterized as they usually were: in sizable groups. These offered them more protection from the depredations of mostly non-Chinese, which usually went unpunished, because California Chinese had virtually no civil rights, hence no protection by the judicial system. After 1852, there were thousands of Chinese gold miners, and by 1870, they constituted a third of the CA gold miners. They tended to mine what others considered less promising areas, and stay longer. Since they weren't allowed to become citizens, they were subject to the Foreign Miners Tax, which often robbed them of 50% of their profit. They were often subject to rapacious fake tax collectors......Sometimes described as a comedic western, the humor is mostly concentrated in one segment , where Fleet enters the bedroom of a sleeping prostitute to claim that he was with her all night, thus could not possibly be one of the train robbers. He had to deal with an idiosyncratic music box he accidentally activated that wouldn't stop playing. Fortunately, the prostitute was a sound sleeper..... See this entertaining film at YouTube.
