When can flagging against the current of traffic in double track be discontinued?

• A. When there is no visibility
• B. Only when the dispatcher advises no movements
• C. When all workers are accounted for
• D. Under no circumstances

Answer: (B)

Flagging against the current of traffic in double track can be discontinued only when the dispatcher advises that there are no movements. This is crucial for maintaining safety in a high-traffic environment where trains operate on both tracks. The dispatcher has an overview of the traffic situation, and their clearance indicates that it is safe to stop flagging, minimizing the risk of accidents or injury to workers on the track. In this context, other potential reasons to discontinue flagging, such as visibility or the status of workers, do not supersede the need for an official clearance from the dispatcher. Ensuring all workers are accounted for is essential for safety but does not address the necessity of ensuring that no trains are approaching. Similarly, flagging cannot be discontinued under any circumstances without dispatcher confirmation, as that would place workers at unnecessary risk.
