Which of the following statements about signal logs is false?

Signal logs serve a critical function in railway operations by recording the status and changes of signals. One of the key aspects of signal logs is that they are essential for maintaining safety and operational efficiency. This makes them a mandatory part of railway documentation, ensuring that all signal changes are documented for reference and compliance purposes.

The assertion that signal logs are optional is therefore misleading. The requirement to maintain these logs underscores their importance in managing train operations and ensuring that safety protocols are adhered to. By documenting all signal changes, operators can effectively manage train movements and respond to any issues that arise, contributing to overall safety and reliability in railway operations.

In contrast, statements about pre-filling, completion in real-time, and the necessity of including all signal changes reflect accurate practices that affirm the importance of signal logs in operational documentation. These practices enhance accuracy and accountability, further highlighting why the option regarding the optional nature of signal logs is indeed false.
