What methods of on-track safety are utilized within manual interlocking limits?

The correct choice highlights important methods of on-track safety that are specifically applicable within manual interlocking limits. Foul time is a crucial safety measure designated to prevent trains from entering a defined area while maintenance or work is being performed. This ensures that workers can operate safely within the limits without the risk of approaching trains.

Lookout serves as a visual safeguard. A lookout is typically assigned to monitor approaching trains and alert workers to any potential dangers, ensuring that everyone is aware of the surrounding conditions and can react promptly in the event of an oncoming train.

Verbal safety checks are an essential communication practice. This involves personnel confirming safety measures and work authorizations, ensuring that every team member is aware of their responsibilities and the current track conditions at all times.

Together, these methods establish a structured approach to safety for personnel working within manual interlocking limits, enhancing overall situational awareness and reducing the risks involved in train operations.

The other options include different methods that could be relevant in various operational contexts, but they don’t specifically address the comprehensive safety measures that are particularly pertinent within manual interlocking limits.
