Goofs

When Sid is making his deal with Barrows, he dips his small cigar in a shot glass twice between shots.

Position of Mollie's left arm when Jeff starts to read his letter on the handcar.

When Jeff meets Dick at his hiding place and asks for a light, the match Dick hands him is unlit, then suddenly flaming.

When Jeff lights his pipe with the match from Dick: The pipe moves from the left side of his mouth to the right side between cameras shots.

The golden spike ceremony shown in the movie is not true. The golden spike was lowered into an auger hole not driven. Gold is a soft metal and striking it as they did in the movie would have severely damaged it. The original golden spike now at Stanford University shows no mallet marks on the head.

After the train wreck, and during all the scenes that immediately follow, Barbara Stanwyck suddenly appears with a very stylish 1939 bobbed hairstyle which we had not seen before, clean fresh makeup, and a 1939 dressing gown, complete with shoulder pads, which, of course, is completely inappropriate to the time period during which the story is taking place.

All handguns shown are the Colt Single-Action Army Model of 1873. The golden spike was inserted at Promontory, Utah in 1869, four years before this revolver model was made.

The chase sequence after the train robbery is shown in mountainous terrain. The robbery supposedly takes place between Cheyenne and Pine Bluffs Wyoming (from geographic references to the train's location in the telegrapher's office). There are no mountains in this area.

The reference in the film to the joining of the rails at Promontory Point is incorrect. This location is 30 miles south of Promontory, or Promontory Summit, where the golden spike was inset.

Mollie's Irish accent comes and goes frequently throughout the picture.
