Which of the following is NOT an area in which a good faith challenge can be raised?

The selection of routes is not considered an area in which a good faith challenge can be raised primarily because it pertains to the broader operational discretion of train movement and scheduling rather than immediate safety or compliance concerns like the other areas listed. A good faith challenge typically applies to specific operational actions where an employee believes a safety or procedural standard has not been met.

Handling of switches, handling of equipment, and leaving equipment in the clear all directly relate to immediate safety issues and compliance with operational standards that can be clearly observed and challenged on-site. These actions have a tangible impact on train operations and safety protocols, making them suitable for challenges based on good faith. In contrast, the selection of routes is often determined by multiple factors including service requirements and overall system efficiency, making it a less appropriate area for raising a good faith challenge.
