While the film used an antique train for its American West segment, the interior of Phileas Fogg's railroad car was an elaborate set mounted on a railway flatcar. Portions could be opened or closed as required to place cameras to catch the action inside the car. Normally a film company would use a set in a studio and use rear projection to provide the background seen through the windows. Producer Todd was not happy with the quality of rear projection shots and was determined to eliminate them as much as possible. The finished film had only one rear projection shot and it is evident that Todd was correct in his assessment of the process.
