What does the conductor's signal indicate?

The conductor's signal is primarily meant to communicate specific directions for the engineer to follow. This may involve instructions for various operational aspects such as starting, stopping, or making specific maneuvers while the train is in motion. The conductor serves a crucial role in ensuring coordination between the train crew and operates as a key communicator, especially in complex scenarios where multiple signals and instructions need to be conveyed to maintain safety and efficiency.

While signals might affect understanding around time for a station stop, weather conditions, or speed adjustments, those scenarios typically would be communicated through different channels or protocols rather than solely relying on the conductor's signal. Therefore, the signal's main purpose revolves around delivering clear directives for the engineer to follow during train operations.
