Why are train operators instructed to operate from a standing position in the yard?

Operating from a standing position in the yard is essential for train operators primarily because it allows them to maintain a high level of situational awareness regarding their surroundings, particularly with respect to tracks and personnel. This position enables them to have a clear line of sight, ensuring they can see anyone near or approaching the track.

Safety is the utmost priority in railway operations, and being able to spot individuals who may be in close proximity to moving trains or other equipment is critical to preventing accidents. While other factors, like communication and alertness, are also important, the ability to visually monitor the area around the tracks directly contributes to operational safety in a yard environment.
