If there are no emergency alarm boxes along a trackway, what can trackmen not do?

When there are no emergency alarm boxes along a trackway, trackmen cannot shut off power. This limitation is crucial for maintaining safety protocols on the railway. Emergency alarm boxes are essential for enabling swift communication in urgent situations, and their absence means that trackmen do not have a means to immediately alert the appropriate authorities or mechanisms to turn off power when necessary to avoid accidents or mishaps.

Being unable to shut off power during an emergency can lead to dangerous situations, especially if trackmen need to perform work near the tracks or if there is an incident that could put them and trains at risk. The inability to communicate effectively in emergencies limits trackmen's ability to ensure safety protocols are followed and can compromise the overall safety of the rail operations. Therefore, the power shut-off capability is a critical component of their safety measures, and without it, they are hampered in their operational duties.
