Under what condition can small groups enter the tracks?

Small groups can enter the tracks provided each member has an approved light. This condition is essential for ensuring safety and visibility in potentially hazardous areas such as train tracks, where awareness of surroundings is critical. An approved light indicates that the individuals can be seen by train operators and other personnel, reducing the risk of accidents.

Appropriate lighting is vital in operational protocols on or near tracks as it enhances visibility, especially during low-light conditions. This requirement works hand-in-hand with safety measures that aim to prevent accidents involving trains and personnel on the tracks. Therefore, having an approved light is a necessary safety measure for small groups intending to access track areas.
