What signals will be displayed on the rear of every train at all times as a marker?

In this context, it is essential to understand the purpose of rear markers on trains, which serve as safety signaling to indicate the presence and status of a train towards the rear when operating on the tracks.

Both amber and red signals are crucial for ensuring safety. The amber light provided by an electric flasher denotes that a train is operating and is particularly visible for other trains approaching from behind, alerting them to the presence of the train. Meanwhile, the fixed electric marker illuminated in red serves as a stop signal, indicating to other trains that they should exercise caution and be aware this is the last car of the train.

Having both types of markers illuminated at the rear enhances visibility and communication on the tracks, promoting safe operation procedures. This dual function is critical in railway signaling, ensuring that all personnel and equipment in proximity to the train are aware of its presence and can act accordingly to maintain safety on the railroad.
