What does the Absolute Block Signal indicate to the train operator?

The Absolute Block Signal indicates to the train operator that it is safe to proceed at slow speed within interlocking limits. This type of signal is designed to ensure that trains are controlled and managed effectively within a specific block section of track. The indication to proceed at a slow speed allows the operator to be cautious and alert, ensuring that they are prepared to stop if necessary. It is important for safety, especially when operating in areas where track switching and other train movements can occur, as it helps prevent collisions and maintains the smooth flow of rail traffic.
