What type of signal is given with both arms raised above the head?

When both arms are raised above the head, it indicates a "Prepare to halt the train" signal. This visual cue is significant in train operations as it alerts the train operator to reduce speed and prepare for a stop. Clear communication through hand signals is essential for ensuring safety in railway operations, and this particular gesture signifies that the train needs to be brought to a halt.

In train signaling systems, precise interpretations of signals are crucial for maintaining safety on the tracks. A signal to prepare to halt means that the operator should expect a potential stop due to upcoming track conditions or signals ahead. This helps prevent accidents and ensures the smooth operation of train services.

Understanding the context and meaning of each signal is vital for a train operator, as it directly influences their responses to various situations on the railroad.
