Visible crew/equipment: When the train cars are decoupled, behind the vapor cloud, a person is hanging from the left side of the train car but does not resemble any of the characters in the scene. (01:47:00)
Visible crew/equipment: While Devereau is burning the Rembrandt Letters, in the background view out of the train window, camera equipment and crew can be seen in the reflection in the windows of the buildings. Also, in the same scene, some people are standing, posed very unnaturally in front of the windows, blocking only some of the reflections. (01:29:20)
Answer: Most likely it was a production decision. Having multiple extra actors continually smoking during multiple takes and over hours of filming would make for a smokey set, affect breathing and burn peoples' eyes, be a fire hazard, and create consistency problems with cigarettes being in various stages of use (freshly lit or almost down to a stub).
