What does a "go slow" signal instruct a train to do?

A "go slow" signal is specifically designed to notify the train crew to proceed at a reduced speed because there may be conditions ahead that require careful handling. This could involve track conditions, potential obstructions, or signals that have not yet cleared ahead. The purpose of this signal is to ensure the safety of the train operation by allowing the engineer to maintain control and prepare for any situations that may arise further down the track.

In railway operations, proper adherence to signals is crucial for maintaining safe distances between trains and reacting appropriately to changes in the environment. The "go slow" signal is a precautionary measure, guiding the train to operate at a speed that takes into account the need for heightened vigilance or adjustments due to external factors.

By understanding this signal's function and the rationale behind it, train crews can effectively manage speed and safeguard against potential accidents or incidents that can occur if full speed is maintained under uncertain conditions.
