What general principle applies when operating an interlocking machine?

When operating an interlocking machine, the principle of avoiding setting switches without verification is crucial for ensuring safety and reliability in train operations. This approach helps in preventing accidents or incidents that could arise from incorrectly set switches. Verification procedures are designed to confirm that switches are in the correct position and that all safety protocols are observed before allowing trains to proceed.

This principle emphasizes the importance of confirming the operational state of track apparatus to maintain a safe railroad environment. Interlocking systems are complex and require careful management of track and signals to ensure that trains can operate without risk of collision or derailment. Following this principle also aligns with broader safety protocols in the railway industry that prioritize verification and validation before any operational changes are made. Adhering to this practice signifies an understanding that safety is paramount in rail operations and that thorough checks are essential for maintaining the integrity of the railway system.
