Which LITR publication provides instructions for conducting initial terminal brake tests?

The correct choice is the THEM manual, which stands for the Train Handling and Engineering Manual. This publication is specifically designed to offer detailed instructions and guidelines related to train handling procedures, including conducting initial terminal brake tests. It encompasses the necessary protocols and safety considerations for ensuring that brake systems function correctly before a train departs from a terminal.

This focus on brake testing is crucial, as it directly impacts the safe operation of trains. Brake tests verify that all braking systems are operational, ensuring that the train can stop effectively as needed. By relying on the specifics provided in the THEM manual, train personnel can maintain compliance with safety regulations and operational efficiency when conducting these essential tests.

The other options, while related to various operational aspects, do not specifically address the procedures for conducting initial terminal brake tests as comprehensively as the THEM manual does.
