What must be connected after making a coupling?

• A. Electrical connections only
• B. Hoses, electrical connections, and chains
• C. Only hoses
• D. Only crosswalk chains

Answer: (B)

After making a coupling, it is essential to connect hoses, electrical connections, and chains in order to ensure the proper functionality and safety of the train. Hoses are crucial for the air brake system; they allow for the necessary air pressure to be maintained throughout the train. The electrical connections are vital for the operation of various systems on the train, including lighting and other electronic functionalities. Chains, specifically crosswalk chains, play a role in securing the coupling and ensuring that the two coupled vehicles remain connected during operation. Thus, connecting all three components—hoses, electrical connections, and chains—ensures that the train functions properly and safely, which is why this option is correct. The omission of any one of these components could lead to failures or safety hazards during operation.
