After Distributed Power testing by mechanical forces, how must each consist be set up?

• A. Each consist must be set-up as an individual conventional consist, air tested, and loading
• B. All consists must be merged into one DP unit
• C. Only headend is tested
• D. Testing is optional

Answer: (A)

In distributed power testing, each consist must be prepared and tested separately as a conventional unit, with an air test and a loading test. This ensures that every unit’s brake system and air lines are intact and functioning, and that the car or locomotive structure and couplings can handle the expected loads. Merging all into a single DP unit would hide individual unit issues and complicate troubleshooting, while testing only the headend would leave trailing units unverified. So the correct approach is to treat each consist as its own conventional unit, air-test it, and perform loading.
