That would largely have to do with the time and location of the filming of Danger Lights. It was filmed Largely in Miles City, MT and in a few other locations around the MT area (Sixteen Mile Canyon) along with Chicago, IL of course.
Timing is the other factor. Danger Lights is a 1930 film, largely filmed in 1929, the year the N3 rebuilds started. It is likely not many of them were either complete or working in the area of Miles City at the time of filming.
Like their original designs, the N3's were found in both regular service and pusher duty on the Chicago, Milwaukee & Puget Sound Lines; even after the electrification of the mainline of the from Tacoma to Othello, WA (hence the stack deflector, for the numerous tunnels along the Pacific extension).
They could be found running on the Elk River branch and the entirety of the non-electrified section of the Pacific Extension in Idaho. Another area where they saw use was the Everett Branch in WA, on the Coast Division.
