What must a tower operator do when expediting service?

When expediting service as a tower operator, maintaining station platforms and model boards is essential for ensuring efficient and safe operations. This responsibility encompasses ensuring that the area is clear for train movements, which is crucial in minimizing delays. The operator must also ensure that model boards accurately reflect the current train schedules and positions, providing vital information to crews, dispatchers, and other operators.

By keeping the platforms well-managed, operators contribute to the overall flow and safety of train operations, thus expediting the movement of trains. This role supports not just the immediate efficiency but also the broader safety protocols in place at the station, helping to prevent accidents and ensuring a smooth transit experience for both passengers and crew.
