What does a 'Red Flag' signify in track safety?

A 'Red Flag' serves a critical role in track safety as it signals a danger or stop condition. This visual indicator is used to alert workers and train operators to hazardous situations that require immediate attention or action. The red color universally represents caution or the need to stop, making it an effective way to communicate serious safety concerns on the track.

In this context, the use of a red flag helps to ensure that all individuals in the vicinity recognize the potential threat and take appropriate measures to safeguard themselves and others, thus minimizing the risk of accidents or injuries. The emphasis on safety and immediate recognition of danger is paramount in creating a secure working environment within railway operations.
