How can you differentiate between a Restricted Proceed indication and a Stop indication when looking at a block signal?

A Restricted Proceed indication can be differentiated from a Stop indication primarily by the presence of a number plate on the signal. A number plate is specific to Restricted Proceed signals, which provide train operators with specific instructions to proceed with caution while limiting the maximum allowable speed. This is an important safety measure, as it indicates that the train cannot proceed at full speed and must remain vigilant for possible obstructions or other hazards.

In contrast, a Stop indication typically does not have a number plate and signifies that the train must come to a complete stop. Understanding this distinction is crucial for conductors and train crew members to make informed decisions while navigating the rail network safely. The presence of a number plate serves as a clear indicator for the conductor to be aware of the restrictions in place and approach the situation with appropriate caution.
