Red Signals was one of a series of low-budget railroad pictures made by Australian-born director J.P. McGowan, including The Open Switch (1925) and Crossed Signals (1926). Leading man Wallace McDonald had a career in Hollywood dating back to the 1914 Charlie Chaplin feature Tillie's Punctured Romance. At the time, Earle Williams, playing McDonald's brother in the film, was actually better known, having starred in another wildly successful railroad melodrama, The Juggernaut (1915) and having played the titular thief in Vitagraph's version of Arsene Lupin (1917). While Red Signals was still in release, Williams died of bronchial pneumonia at the age of 47. Shot in Los Angeles, Red Signals also serves as a photographic record of Santa Fe's La Grande Station, which was damaged in the 1933 Long Beach earthquake and finally demolished in 1939.
