What must be obtained before making a reverse movement on the track?

Before making a reverse movement on the track, it is essential to obtain permission from the train dispatcher or control operator. This requirement is crucial for ensuring safety and operational efficiency. The train dispatcher or control operator has the overall responsibility for managing the train movements within the railway network. They provide the necessary clearances and instructions to ensure that the track is safe for a reverse movement, taking into account the position of other trains, signals, and any potential hazards on the track.

While authorization from a shift supervisor, a safety briefing from crew members, and documentation of train length are important aspects of overall operational procedures, they do not fulfill the specific requirement of ensuring the track is clear and safe for reverse movement. The dispatcher or control operator’s authority is crucial because they have the visibility and information about the entire rail network, which is vital for making informed decisions regarding train movements.
