The employee performing the cab signal test must post a signed copy of the test results where?

• A. In the cab of the locomotive only
• B. At the test location only
• C. In the cab of the locomotive and must leave a signed copy of the test results at the test location
• D. On the bulletin board

Answer: (C)

Recordkeeping and accessibility are essential in cab signal testing. After completing the cab signal test, a signed copy of the results must stay in the locomotive cab so the engineer and crew can review them, and it must also be left at the test location so supervisors have a formal, auditable record. This dual posting ensures both immediate visibility for the crew and proper documentation for compliance and inspection. Posting only in the cab would keep the test results from the test location, and posting only at the test location would deprive the crew of the available results. A bulletin board wouldn’t satisfy the requirement for an official signed copy kept in these specific places.
