Which document describes how to manipulate interlocking machines?

The Manipulation Chart is a critical document when it comes to understanding how to operate interlocking machines effectively. This chart provides detailed instructions and guidelines for the specific movements, sequences, and actions required to manipulate the interlocking system. It includes visual representations, workflow diagrams, or sequences of operations that help operators to understand how various switches and signals interact within the system.

This document is essential for ensuring that the operations are conducted safely and efficiently, minimizing the risk of errors or accidents during the manipulation of interlocking machines. By referring to the Manipulation Chart, operators can ensure that their actions align with the designed operations of the system, contributing to the safe and reliable functioning of railway operations.

While the Operation Manual generally provides broader operational guidelines, the Safety Guidelines focus specifically on safety protocols rather than manipulation techniques. Similarly, the Signal Protocol outlines the communication methods and signals used but does not directly address the operational mechanics of interlocking machines. Thus, the Manipulation Chart stands out as the document specifically dedicated to guiding operators on how to manipulate these systems.
