Here's some interesting info that Cullens character is seemingly based off of loosely... might give an idea how it ends....... He did fight in the indian wars but that happened before the railroad was built... so I'm not sure why they are showing him in army uniform in the preview...... I am thinking Durant somehow ends up causing trouble for Cullen with the government and in the end he goes on the run.... Off to China...
Shortly after building the Union Pacific track to its famous completion at Promontory Summit, Utah,
Dodge resigned his position; he had no taste for a mere desk job. In 1870 he retired for a while to Council Bluffs.
The general was a resolute family man who had kept frequent correspondence with wife Anna throughout construction.
Although Durant had once promised Dodge stock in his secret scam, the Credit Mobilier, it had never materialized.
Dodge had been eager to get in on the windfall, however, and purchased 100 shares in his wife's name. It turned a handsome profit --
341 percent in just 18 months -- but when the Credit Mobilier scandal erupted in 1872, Dodge would claim that his wife bought the
shares from "her own resources," presumably housekeeping money. A congressional committee wanted to know more,
but Dodge had no interest in going anywhere near Washington. Federal agents were sent out, but they could not manage to find him.
Peter Dey, whom Dodge had once replaced as engineer, told Congress that Dodge was "a man of wonderful resources, and can live in Texas all winter,
out of doors, if he wants to, where none of your marshals can go, and if he don't want to come he will not come." Dey proved correct.
