How must movement be conducted to operate a hand throw switch?

To operate a hand throw switch safely and effectively, it is essential that equipment must not foul the track during movement. This requirement is in place to ensure that there are no obstructions within the switch area and that the switch can be operated without risk of interfering with moving trains or equipment. If equipment were to foul the track, it could lead to accidents, derailments, or damage to both the switch and rolling stock.

Having all crew members present may be important for safety and communication, but it is not a strict requirement for the operation process itself. Similarly, while inspection of the switch is a critical practice, it does not directly pertain to the operational aspect of moving through that area. Dispatch communication might be necessary for various operational reasons, but it doesn't specifically apply to the mechanics of operating a hand throw switch. Hence, ensuring that movement does not foul the track is the fundamental principle guiding safe operation in this context.
