What is the primary purpose of the Brake Pipe Leakage Test?

The primary purpose of the Brake Pipe Leakage Test is to check for air leakage in the brake system. This test is crucial because maintaining the integrity of the brake system is essential for safe train operations. Any leakage in the brake pipe can lead to a reduction in air pressure, which may compromise the effectiveness of the brakes. By ensuring that the brake system is leak-free, train operators can confirm that the brakes will function properly when needed, thus enhancing overall safety on the railroads.

The other options revolve around different aspects of train operation and performance but are not relevant to the specific goal of the Brake Pipe Leakage Test, which is solely focused on identifying leaks within the brake system to ensure optimal functionality.
