If a train is moving under a signal requiring restricted speed, can it comply with the next signal's indication?

When a train is operating under a signal requiring restricted speed, the train must adhere to that speed limit until it reaches a clear indication that the train can change its speed or proceed. Restricted speed is often employed in situations where the train must be prepared to stop within half the distance of any visible obstruction and be ready to encounter potential hazards.

In this context, maintaining restricted speed serves several purposes: it allows for increased safety, particularly in areas where track work, other trains, or animals may be present, and it provides the crew time to react appropriately to any signal aspects or situations they may encounter. If the next signal is not visible or clear, the train must continue to operate at restricted speed until such a signal can be observed and interpreted regarding its indication. Therefore, according to the rules, the train is required to maintain restricted speed and cannot simply change its speed based on the next signal's indication without ensuring that the circumstances allow for it.
