How many ground switches must a Class A employee visibly check when obtaining a transmission clearance?

A Class A employee is required to visibly check one adjoining ground switch when obtaining a transmission clearance. This practice is crucial for ensuring the safety and reliability of train operations. By checking one adjoining switch, the employee helps confirm that the section of track is correctly aligned and safe for trains to traverse.

This process mitigates risks associated with misaligned switches, which could lead to accidents or derailments. The requirement to check only one switch emphasizes the importance of thoroughness while balancing operational efficiency. Checking additional switches, while beneficial, is not mandated, as the focus is on ensuring that the immediate area affecting the clearance is secure.

This practice aligns with safety regulations and operational policies that guide proper procedures for employees in the rail industry, emphasizing the critical nature of proper checks before train movements.
