What is the voltage on the Signal Wire?

The voltage on the Signal Wire is 6900V, which is a standard value often used in railway signaling systems. This voltage is specifically designed to ensure safe and reliable communication between various signaling components within the rail system.

The choice of 6900V allows signals to be transmitted over considerable distances without significant loss or degradation, providing clear and consistent communication necessary for the operation and safety of trains. This voltage level is chosen to be effective while still meeting safety standards to protect personnel and equipment from the dangers of electrical components.

Understanding the importance of this specific voltage helps in recognizing its role in maintaining operational integrity and control in the rail network, which is crucial for safe train operations.
