What type of movements does the term 'manual block' refer to?

  1. Automated, signal-controlled movements

  2. Train movements between human-managed signals

  3. Any movements involving freight transport only

  4. Movements involving solely light engines

The correct answer is: Train movements between human-managed signals

The term 'manual block' specifically refers to the protocol governing train movements that are managed by human operators rather than automated systems. In this context, human-managed signals are critical in ensuring that trains move safely and efficiently between blocks. Operators are responsible for controlling the signals which dictate when a train can proceed or must stop, allowing for the safe sharing of tracks among multiple trains. This method is essential in situations where track conditions necessitate manual oversight—such as areas with limited signal infrastructure or during times of construction or other hazards. The use of manual block systems is common in freight and passenger rail services, where active human intervention can help coordinate train schedules and maintain safety in complex rail networks.
