When stopped at a signal displaying a stop indication at an automatic interlocking, what action should be taken if no conflicting movements are evident?

When stopped at a signal displaying a stop indication at an automatic interlocking, the appropriate action is to move at restricted speed upon receiving hand signals. This is because even though no conflicting movements are evident, the stop signal indicates that the train must not proceed at normal speed until it is certain that it is safe to do so.

Moving at restricted speed allows the train to proceed cautiously, enabling the train dispatcher or crew to respond to any unforeseen situations or instructions that may arise as the train moves. In the context of railway operations, it is essential for safety to ensure that the train can stop immediately if needed. The use of hand signals in this scenario indicates that signals are clear to proceed, but with caution, thereby maintaining safety protocols.

The other actions would not be suitable in this situation because proceeding at normal speed ignores the stop indication, waiting for verbal instructions may unnecessarily delay the operation if hand signals are already provided, and immediate reverse movement is inappropriate unless specifically instructed during exceptional circumstances.
