# Danger Lights

Danger Lights is a 1930 American pre-Code drama film, directed by George B. Seitz, from a screenplay by James Ashmore Creelman. It stars Louis Wolheim, Robert Armstrong, and Jean Arthur.
The plot concerns railroading on the Chicago, Milwaukee, St. Paul and Pacific Railroad (Milwaukee Road), and the movie was largely filmed along that railroad's lines in Montana. The railway yard in Miles City, Montana, was a primary setting, while rural scenes were shot along the railway line through Sixteen Mile Canyon, Montana. Additional footage was shot in Chicago, Illinois (where the Milwaukee Road was headquartered until 1986, when it went out of business). The film was the first ever shot in the new Spoor-Berggren Natural Vision Process.
In 1958, the film entered the public domain in the United States because the claimants did not renew its copyright registration in the 28th year after publication.

## Plot

Dan Thorn is a divisional boss on the Milwaukee Railroad, based in Miles City, Montana. The film opens with a landslide across the track and Thorn dispatching, then accompanying, a repair crew to clear it. Several hobos are lounging nearby and are put to work helping the crew. Thorn discovers that one of the hobos, Larry Doyle, is a former railroad engineer who lost his job over insubordination. Thorn finds he likes the man and demands that he better his life by returning to work for the railroad. Doyle repeatedly refuses even as he starts the work, but Thorn is a hard man to say no to, and Doyle is hired.
Thorn is engaged to Mary Ryan, but his job leaves him unable to give her much time or attention. When an engineer's wife dies, Thorn spends time with the man to keep him from getting drunk and endangering his railroad job. This leaves Thorn unable to attend a social event, so he asks Doyle to go with Mary instead. Afterwards, at night, the two are using a long railway bridge to walk home when a fast train approaches. Doyle whisks Mary into a trackside refuge and kisses her as the train rushes by.
Mary still cares for Thorn, but she falls in love with Doyle. Finally he persuades her to run away to Chicago with him and get married. That night, as they walk along the tracks through a rain storm toward the station, Doyle's foot becomes trapped in a railroad switch as it is remotely reset for the train. At this point Thorn approaches and threatens Doyle over Mary, but when he realizes the man is trapped, he manages to pull Doyle clear of the switch at the last moment. Doyle is safe but Thorn is hit by the train and seriously injured.
The local doctor says Thorn will die unless he can be taken to Chicago for brain surgery within five hours, which would require breaking the speed record for the trip. Doyle volunteers to drive a special train and is able to accomplish the feat. Thorn is saved.
Two weeks later, Thorn is taken back to Miles City by train, conscious but depressed. At the station, Mary is the first to board, and promises to return to him. But Thorn says that during his enforced rest he has come to realize that he is already married—to the railroad. He frees her to marry Doyle with his blessing. Then, overhearing railwaymen outside speaking as if he is done for, he shouts at them to get back to work. They do, and his depression lifts.
