What is the required air test before putting a train together at its initial terminal?

The required air test before putting a train together at its initial terminal is the Initial Terminal and Road Air Brake Test. This test is essential for ensuring the safety and operational effectiveness of the train before it begins its journey. It is conducted to confirm that the air brake system is functioning properly and that all components meet necessary standards.

The Initial Terminal and Road Air Brake Test checks the entire air brake system, including the air hoses, brake valves, and the operation of the brakes on each car. It ensures that the system is adequately charged and able to perform under operational conditions. Conducting this test at the initial terminal is a critical step, as it establishes a baseline for the train's braking performance prior to any additional journeys.

Other options offered, while related to air brake testing, serve different purposes and are conducted at different points in the train's life cycle. The Intermediate Air Brake Test (Class 1A), for example, is a more specialized test typically performed on already assembled trains after they have been in operation for some time. The Application and Release Air Brake Test (Class 3) focuses on verifying that the brakes apply and release properly during a specific scenario, but it does not encompass the thorough checks required at the initial terminal.
