In a tower operation system, what is the purpose of the model board?

The model board in a tower operation system serves the critical function of indicating lever positions. It provides a visual representation of the current settings of various levers that control train movements, signals, and other operational aspects within the rail network. By displaying the status of these levers, tower operators can quickly assess the system's configuration, ensuring safe and efficient train operations.

This visual status is essential for maintaining situational awareness and reducing the potential for errors during train operations. It enables operators to confirm that the correct signals are displayed and that levers are positioned appropriately to allow for safe passage through the rail network. In this way, the model board enhances communication and coordination within the tower, which is vital for effective rail traffic management.
