What is the purpose of showing markers at the end of the train?

Showing markers at the end of the train serves the crucial function of denoting the end of the train. These markers, often in the form of flags, lights, or reflective devices, are used to communicate to other rail traffic, maintenance crews, and personnel that there are no cars or components behind the marker. This is particularly important for safety reasons, ensuring that other trains and workers are aware of the complete length of the train and do not inadvertently approach the back end where there may be significant hazards. Without this clear indication, there could be serious safety risks associated with misjudging the length of the train or mistakenly thinking the train has ended prematurely.
